Obamanomics: No to NAFTA & Wal-Mart

From yesterday's speech, via Greg Mankiw:

...t's a game where trade deals like NAFTA ship jobs overseas and force parents to compete with their teenagers to work for minimum wage at Wal-Mart. That's what happens when the American worker doesn't have a voice at the negotiating table, when leaders change their positions on trade with the politics of the moment, and that's why we need a President who will listen to Main Street – not just Wall Street; a President who will stand with workers not just when it's easy, but when it's hard.

This is what the Democratic primaries do to a candidate.
