Twenty-two states enacted 70 measures which sought to tighten abortion laws in 2013, according to Guttmacher's data. The 70 laws accounted for about half of all (141) the provisions nationwide related to reproductive matters. Only 2011 outpaced 2013 in terms of new abortion restrictions.
Some of the legislative battles over abortion last year played out before the national stage. Most visible was a fight in Texas in which state Sen. Wendy Davis (D) launched a marathon filibuster in June to block a bill designed to implement strict new restrictions. The measure later passed as Republicans launched a renewed effort. Still, Davis's resistance catapulted her onto the national radar. She's now a candidate for governor.
In June, the U.S. House passed a 20-week abortion ban that went nowhere in the Democratic-controlled Senate.
The Guttmacher data reflect a reality about the abortion debate that is also true about other hot-button issues like education and guns: Often, what's happening in the states is more consequential than what's happening or not happening in Washington.
