Sen. Pat Toomey (R-Pa.), who championed a bipartisan compromise on gun reforms, has seen his approval rating reach new heights.
On the other, Sen. Kelly Ayotte (R-N.H.) has seen her support back home drop sharply, so much so that she is "underwater" (disapproval is higher than approval).
Yesterday, PPP came out with a poll showing that gun vote hurt others too:
After just 3 months in office Jeff Flake has already become one of the most unpopular Senators in the country. Just 32% of voters approve of him to 51% who disapprove and that -19 net approval rating makes him the most unpopular sitting Senator we've polled on, taking that label from Mitch McConnell.
When we polled Alaska in February Lisa Murkowski was one of the most popular Senators in the country with a 54% approval rating and only 33% of voters disapproving of her. She's seen a precipitous decline in the wake of her background checks vote though. Her approval is down a net 16 points from that +21 standing to +5 with 46% of voters approving and 41% now disapproving of her. Murkowski has lost most of her appeal to Democrats in the wake of her vote, with her numbers with them going from 59/25 to 44/44. And the vote hasn't increased her credibility with Republican either- she was at 51/38 with them in February and she's at 50/39 now.
Mark Begich is down following his no vote as well. He was at 49/39 in February and now he's at 41/37. His popularity has declined with Democrats (from 76/17 to 59/24) and with independents (from 54/32 to 43/35), and there has been no corresponding improvement with Republicans. He had a 24% approval rating with them two months ago and he has a 24% approval rating with them now.
We saw serious improvement in Rob Portman's poll numbers in the second half of 2012 following his consideration as the Republican Vice Presidential candidate, but he's taken a nose dive in 2013. Portman's approval has dropped a net 18 points over the last 6 months from +10 (35/25) in October to now -8 (26/34) in April. Portman's popularity decline has come across the board with Democrats (from 15/39 to 8/50), Republicans (62/11 to 46/19), and independents (28/23 to 24/32) alike.
And in Nevada Dean Heller has seen a more modest decline in his approval numbers, from 47/42 right before the election to 44/41 now. However with the independent voters who were critical to his narrow victory in November, his approval has dropped from 52/37 then to now 42/42.
Taken together these results make it pretty clear that this issue could be a serious liability for the Senators who opposed overwhelmingly popular background checks in the Senate vote earlier this month.
Let's hope the voter resentment stays until election day.
