I wouldn't call the election a lock yet. After the first debate, then maybe Obama can afford to send some money downballot.
Yeah, but even then I doubt he will. He didnt in fall 2008 when he was a lock and Democrats did far worse in the House than anybody expected. If he had simply campaigned for Franken in Minnesota in the final days of the election, that race would have been more clear cut and Franken would have been seated immediately rather than seven months later.
Even Bill Clinton campaigned for Boxer in 1992 near the end when it looked like she was in trouble against Herschonson and for Harkin, Johnson, and Swett in 1996. Obama should be doing the same.
