CHICAGO (AP) — Sen. Tammy Baldwin, facing a tough reelection fight in one of the races that will determine control of Congress, has made protecting reproductive rights a cornerstone of her campaign, and she’s willing to back that up by pledging to change the Senate filibuster rules if Democrats retain control of the chamber.

The Wisconsin Democrat said taking that step is necessary to ensure that women in every state -– not the government -– can decide for themselves whether to have an abortion. As part of her campaign, she warns that Republicans might also target the filibuster to impose a national abortion ban if they prevail in November.

“Republicans have shown time and again that they will stop at nothing in their pursuit of controlling women’s bodies – and I believe them,” she said.

Democratic incumbents and challengers running for the Senate this year say they want to restore a national right to abortion, and many, like Baldwin, openly say they would support suspending the filibuster to do so. It’s become a key talking point as they try to capitalize on the nationwide battle over abortion rights that has generally helped Democratic candidates since the Supreme Court overturned constitutional protections two years ago.
