A major anti-abortion group will give Rep. Steve Driehaus (D-Ohio) a pass on some of his prior votes if he follows through on his pledge not to support the healthcare reconciliation bill.

"If Mr. Driehaus stands up to the president and the speaker and votes against the most pro-abortion, single bill ever to reach the House floor, he deserves a Medal of Valor and the gratitude of the pro-life movement," Douglas Johnson, legislative director for the National Right to Life Committee, told the Ballot Box.

Driehaus said Monday: "I will not bend on the principle of federal funding on abortion. … They are going to have to do it without me and without the other pro-life Democrats."

But because of some of his past votes, Driehaus has only a 50 percent rating from National Right to Life -- something his likely Republican opponent wants to exploit.

"If he wants to have this election be about pro-life, bring it on because he's got a 50 percent score right now with National Right to Life," said former Rep. Steve Chabot (R-Ohio). "He voted against the Pence amendment -- he voted to give tax dollars to Planned Parenthood."

Chabot had a 97 percent career rating from National Right to Life.

But Johnson noted that Rep. Bart Stupak (D-Mich.) -- who has gained notoriety for his anti-abortion stance during the healthcare debate -- has the same rating from the group as Driehaus.
