IT WAS ALWAYS A TIGHT RACE:

The latest poll, released Aug. 3 by Gravis Marketing for the conservative website Human Events, shows Walker and Burke tied at 47 percent each among likely Wisconsin voters. In March, Gravis had Walker up by 5 percentage points. A poll released July 23 by Marquette University Law School in Milwaukee shows Walker at 46 percent and Burke at 45 percent among registered voters.

A source in the Walker camp speaking privately says Wisconsin Democrats are more engaged and energized by the race than Republicans - a reverse from the national trend, and a worrisome sign for the GOP in a blue-leaning state.
