Candidates Plunge Into Tsunami

On the biggest primary voting day in American history, the Times offers snapshots of the four major campaigns:

• Mitt Romney has finally settled on a pitch as he’s become the underdog: He's a populist insurgent.

• Barack Obama’s crowds just keep growing, and the candidate turns the attention into energy. Policy specifics have disappeared from his speeches.
• John McCain is uncomfortable as frontrunner, superstitious about making predictions, and looking especially tired.
