- Hillary Rodham Clinton is looking at a trust deficit in key battleground states
- Jeb Bush is taking heat for saying the phrase, 'anchor baby,' but Donald Trump uses it unapologetically
- Bush and others talked up vouchers and school choice, and talked down Common Core at a forum on Wednesday
- Martin O'Malley is trying to stir up some excitement for his bid in California
- Marco Rubio will deliver remarks on his middle-class economic agenda at the Detroit Economic Club
