President Bush was with Congressman Mike Sodrel yesterday. (You can contribute to Sodrel here.)
Given the superb nature of the GOP GOTV and the polling operation it runs, watching where the president goes over the next nine days will be a much better "leading indicator" of which way the House and Senate are going than even Tradesports, (though as Powerline points out, Tradesports looks good for the GOP retaining control of the Senate.)
The Los Angeles Times has a piece on the political operation rolling out this week. It is great fun to watch, even when the press box is pulling for the other team.
