Missouri Rep. Todd Akin is still campaigning — and his controversial comments about rape are continuing to impact the high-profile U.S. Senate race in Massachusetts.

On Aug. 21, Sen. Scott Brown sent a letter to the chairman of the Republican National Committee, asking him to drop the anti-abortion plank in the party platform.

Peter Blute, the deputy chairman of the Massachusetts Republican Party, said sending the letter was a brave move. "I think it’s very rare that a senator stands up and speaks against a plank in his own party’s platform."

But Megan Amundson, the executive vice president of NARAL Pro Choice, said the letter didn't go far enough.

“The letter doesn’t do anything. He’s been very clear the letter is all he’s willing to do. That’s he’s not willing to go to the convention to speak about for this or fight for this, that’s he’s not willingly to actively stand up for women’s rights,” she said.

Brown said on Aug. 22 that he wouldn’t be taking the abortion fight to the GOP convention in Tampa this weekend.

“I’m going down Thursday as I’ve always planned before this came up," he said. "They know my position. It’s up to others to join forces. The Olympia Snowes and Collinses need to join forces.”

In the past, other big-name Massachusetts Republicans did more than write letters about abortion. In 1992, then-Gov. Bill Weld delivered a strong pro-choice speech at the Republican Convention in Houston. He tried to launch a floor fight but didn’t have enough votes. 

Brown’s challenger Elizabeth Warren has capitalized on this issue. All this week she’s been hammering Brown on abortion, contraception and equal pay.
