Republicans are putting immense pressure on Missouri Senate nominee Todd Akin to drop out of the race amid the furor over this comments on rape. One of the most tangible sources of pressure is pulling money out of the state, giving the appearance that they won't help Akin if he remains in the race. But Republicans have yet to cancel their big fall ad reservations in Missouri, according to a Democratic source tracking ad buys.
Crossroads GPS had a new round of ads scheduled to start Wednesday in the state, and pulled that buy. But Crossroads hasn't yet cancelled a $2.2 million buy running from September 11 to October 1.
And National Republican Senatorial Committee chair John Cornyn told Akin they wouldn't spend money on the race, an NRSC aide told the Washington Post. But so far, the NRSC hasn't touched a $4.3 million ad reservation from October 10 through Election Day. An NRSC aide says they're not bothering pulling the buys before Tuesday, but will do so if Akin stays in past 5:00 p.m. tomorrow.
Meanwhile, Akin tweeted Monday afternoon that he is "in this race to win" and soliciting donations.
