Sen. Mark Warner (D-Va.) said he believed Rush Limbaugh's controversial comments about Georgetown Law student Sandra Fluke were "way out of bounds" and blasted Republicans for their stance on social issues during a Twitter town hall meeting Wednesday.

The Virginia lawmaker solicited questions from Twitter users, asking them to tweet using the hashtag #askwarner to participate in the online townhall.

Warner fielded multiple inquiries on reproductive rights, using the issue to hammer Republicans.

Limbaugh famously called Flake a "slut" and a "prostitute" after she testified in favor of a rule that would require employers to provide free access to contraception.

Democrats believe the issue of reproductive rights could be especially potent in Virginia, a pivotal swing state in November's election. A high-profile Senate showdown between former governor and DNC Chair TIm Kaine and former Sen. George Allen has only increased focus on the state.

A Quinnipiac University poll released Wednesday showed that Republican governor Bob McDonnell's approval rating has dropped to his lowest rating since the university began polling the state in June, 2011, a number Democrats attribute to support for legislation that would require an ultrasound before an abortion procedure.

Women who approve of McDonnell dropped from 54 percent to 49 percent, and those who disapprove of his job spiked from 25 percent to 34 percent. Those numbers have Democrats in the state eager to keep the issue in the headlines, hoping they can win over independent voters that will be crucial in November.
