Sen. Kirsten Gillibrand sent out a fundraising appeal for Sen. Claire McCaskill this afternoon in the wake of the Missouri Democrat’s opponent’s remarks on rape and pregnancy.

“In all my years of public service, I’ve heard a lot of shocking remarks on the campaign trail. But yesterday’s appalling comment by Tea Party senatorial candidate Rep. Todd Akin of Missouri took things to a whole new level,” Gillibrand writes in the fundraising email.

McCaskill was seen as perhaps the most endangered of the Senate Democrats running for re-election this year (Gillibrand has made a point of conducting her “Off the Sidelines” campaign to elect more women to public office, a narrative that her own GOP opponent, Wendy Long, has gleefully sought to turn on its ear).

Give to the McCaskill for Senate campaign as soon as you can and make your voice heard. Even just $5 will make a real difference in this extremely tight race.

For now, Rep. Todd Akin remains in the race, though the pressure being brought on him to drop his Senate bid in a state that’s hotly contested at the presidential level is surely enough to crush a deep-sea subamarine.

Perhaps a little ironically, it was McCaskill who preferred to face Akin to his Republican primary opponents, running ads that described him as “the most conservative.”
