There’s been a lot of talk in this race about what makes a "real man." A man does what’s right when no one is watching. He upholds his commitments to his family and neighbors. He doesn’t lie, cheat, & steal his way through life. Real men serve others. Weak men serve themselves.

From our magazine: GOP legislators repeatedly insisted that “Texas Education Freedom Accounts” would be open to any and all types of private schools—of all creeds and persuasions. In predictable fashion, they haven't quite lived up to that promise.

School Vouchers Are What We Thought They Were
The nascent "freedom accounts" program is, predictably, burdened by Republicans’ insistence on religious discrimination—and likely set to benefit those already outside the public school system.
