Paul Krugman: Will the Levee Break?

The conventional wisdom says that the Democrats will take control of the House of Representatives next month, but only by a small margin. I’ve been looking at the numbers, however, and I believe this conventional wisdom is almost all wrong.

Here’s what’s happening: a huge Democratic storm surge is heading toward a high Republican levee. It’s still possible that the surge won’t overtop the levee — that is, the Democrats could fail by a small margin to take control of Congress. But if the surge does go over the top, the flooding will almost surely reach well inland — that is, if the Democrats win, they’ll probably win big.
