Sen. Rob Portman's, R-Ohio, approval ratings have dropped marginally since he announced he supported same-sex marriage last month, according to a Quinnipiac University poll released Friday. The poll shows Portman with 40 percent approval, while 31 percent of voters take a negative view of his job performance. That's down from a 44-24 margin a in a Feb. 28 poll.
Notably, 41 percent of Republicans take a less favorable view of Portman since his announcement. His approval splits among GOP voters dipped from 63-8 to 57-21, while rising slightly among Democrats.
The poll also found that Ohio voters favors same-sex marriage by a 48-44 margin, with women significantly more likely to support it. Twenty percent of voters said their view of Portman has improved since he declared his support for gay marriage, 25 percent think less favorably of him and 53 percent say it has not changed their perception of him.
Portman is not up for reelection until 2016, but he drew an early challenger Wednesday. State Rep. Bob Hagan vowed on Twitter that he would run against him following his vote against expanded background checks, which are supported by 84 percent of voters, the poll shows. Moreover, a 52-percent majority of voters said they would be more likely to vote for their member of Congress if that member voted for requiring background checks for all gun buyers. Only 15 percent said it would make them less likely.
The Quinnipiac poll also found that President Obama's approval in Ohio has dropped to 45 percent, and that a slight plurality of voters favor Gov. John Kasich's plan to expand Medicaid, which has been stymied by the GOP-controlled state legislature.
The Quinnipiac poll was conducted April 10-15, surveying 1,138 registered voters. The margin of error is plus-or-minus 2.9 percentage points.
