While not perfect, JFK and his brothers were smart, compassionate leaders who sought a better world and dedicated their lives to helping those less fortunate. In sharp contrast to Pres. Trump, whose obsession with self-aggrandizement is obscene and whose name should not be on JFK’s living memorial.

Sen King made a mistake in voting in favor of the GOP Congress’s recent “CR”, yet he’s spot-on in his assessment of the Trump Admin’s efforts to strong arm Ukraine into accepting an unacceptable “peace” agreement. US needs to place more pressure on Russia, not Ukraine!

While it’s healthy to criticize DEM Party leadership decisions, it’s wrong for DEM candidates to infer that the DEM Party is just as bad or as corrupt as the GOP. It's intellectually dishonest and harms the DEM Party’s efforts to succeed more broadly and address USA's most pressing challenges...

While cost-of-living concerns ranks highest, “A House of Dynamite” and Pres Trump’s call for renewed nukes testing highlights the need to reprioritize nuclear disarmament talks and the replacement of the concept of mutually assured destruction (MAD) with that of mutually assured deterrence...

While not a fan of “horse race” political journalism (too superficial), it is interesting that I placed third in UNH’s recent Maine US Senate race poll ahead of Jordan Wood whose campaign has already spent more than $2.1 million and has also enjoyed considerably more press attention...

I, and beagle Stella, think that I'm the best (most electable) Democrat to take on Senator Collins in 2026. Because I possess genuine working-class Maine roots and broadest public service experience, and I committed to advancing the boldest policy reforms. More information costelloforsenate.com

Gov Pritzker is right. The Trump Admin’s deployment of troops has little to do with fighting crime (better addressed locally with more federal funding) and almost everything to do with intimidating political opponents and boosting the President’s tough guy persona. 90% political theater #MEpolitics

Glitzy/loud campaign videos tend to garner more attention, yet candidate background, knowledge, and experience ultimately matter more (costelloforsenate.com) Effective governance is generally boring. Don’t fall for the noise and glitz #MEpolitics

Maine voters are urged to vote NO on Question 1, a GOP organized effort to make it more difficult for Mainers to vote by absentee ballot and YES on Question 2, an initiative to enact a common-sense Red Flag gun safety law in Maine #MEpolitics

Scoring political points by wrongly attacking the supposedly ill-intentioned DEM Party establishment will not aid the greater cause of thwarting the Trump Admin and its GOP allies, nor help in enacting long-overdue democratic reforms. Smart DEM candidates know better. Read medium.com/@grace.coste...

Pres. Trump’s assault on free speech, a free press, and America’s elite scientific, legal, and cultural institutions is crippling our already flawed democracy. To alter course, we must win control of Congress. To protect against future assaults, we must enact a host of long-overdue reforms.

The American people, including a majority of her own party, support transparency and accountability. But this week Susan Collins cast the deciding vote to block the Epstein files from being released. I’m running against her for US Senate because the people of Maine deserve better.

Political violence is never justified We should all be very upset that Charlie Kirk was assassinated yesterday. Political and ideological differences of opinion should be vigorously debated and resolved democratically; they should never involve violence.

Pay-to-play politics is the corrosive root of countless problems facing our county. That’s why I’m running to replace Susan Collins and represent the people of Maine in the US Senate.

Please share: My name is David Costello. I am a lifelong Mainer and Democrat running against Susan Collins. I too am concerned. I am concerned with endless decisions Susan Collins has made. We need to turn a page, retire Susan and take back the US Senate. Please watch and share:

It’s reprehensible that Pres. Trump continues to back away from stalwart support for Ukraine. NATO allies are right to be concerned about the kind of “peace” deal that Trump might cut with Putin. Trump’s desire for attention and perceived “wins” jeopardizes everyone’s long-term security. #UkraineWar

The Trump Admin’s escalating attacks on clean energy are unconscionable. They’ll kill critical jobs and projects, increase electricity and climate impact costs, and harm public health and the environment. It’s time for Sen. Collins to step it up or step aside! #MEpolitics #DefeatSusanCollins

To end the Trump Admin’s reckless assault on our values, democracy, and environment; repair damage already done; and enact long-overdue systemic reforms. We first need to win control of the US House and Senate. #MEpolitics #DefeatSusanCollins

To ensure that all are provided with the education, healthcare, and other life enriching opportunities to thrive, we need to enact long-overdue reforms (see costelloforsenate.com), including overhauling our deficient checks and balances system #MEpolitics #DefeatSusanCollins

The breadth and depth of the damage being wrought by the Trump Admin is unparalleled and beyond frightening, and Senator Collin’s inability after 28 years in the senate to marshal any credible opposition, other than “concern,” is unacceptable. #MEpolitics #DefeatSusanCollins

The Maine Democrat with the background and extensive public service experience to defeat Sen. Susan Collins in 2026 #Mepolitics #DefeatCollins

Compelling candidate contrast: Senator Susan Collins (wealthy well-connected business family, lifelong politician) versus Democrat David Costello, (working-class family, 30+ years of senior-level public service experience in the U.S. and abroad). Costelloforsenate.com #MEpolitics

To defeat Senator Susan Collins, Democrats would do well to back a candidate whose background and experience poses a significant contrast to Collins: a senator who has accomplished little beyond electoral success in 28+ years. Visit: Costelloforsenate.com #MEpolitics

USAID ceased to exist on July 1, and its reckless demise will likely haunt American foreign policy for years to come. I was proud to work for USAID (90s and early 00s). USAID helped to stabilize ravaged countries, saved countless lives, and mitigated the migration of thousands of refugees. #USAID

In 1996 Sen. Susan Collins supported term limits and said she would “only serve two terms...twelve years was long enough” She also criticized her opponent for being an “Energizer Bunny” who “just keeps running and running and running...in election after election.” Really Susan? #mepolitics

Not surprisingly, given that 1 in 4 families in Maine will be harmed, Senator Collins was given a pass by the Trump WH and GOP leadership to vote against the GOP’s disastrous debt-exploding and safety-net slashing “Big, Beautiful Bill.” Legislation she was obliged to have opposed more vigorously.

Susan Collins must do far more than merely express concern, propose tweaks, or cast a hesitant vote against the Trump Administration and GOP Congress’s disastrous “Big, Beautiful Bill.” This deficit-ballooning, wealth-favoring budget reconciliation bill is a direct attack on Maine’s working families

Expressing concern, tweaking, and voting against the budget reconciliation bill will not suffice. Sen. Collins needs to kill the Trump Admin’s and Congress’s deficit/debt exploding tax cut and safety-net slashing bill. A bill that will harm many more than it will protect or benefit #MEpolitics
