(CNSNews.com) - Union support for President Obama is "by no means monolithic," a new Gallup poll says.
While 57 percent of union members who are registered to vote would support Obama in 2012, 35 percent said they would vote for his Republican challenger Mitt Romney.
(For the record, an Edison exit poll showed that Obama received 59 percent of the union vote in 2008, compared with 39 percent for Sen. John McCain.)
The latest Gallup poll, conducted April 11-June 5, 2012, shows that government union workers are about the same as private-sector union members in their preferences: Union members who work for the government -- public sector employees -- went 34 percent for Romney and 59 percent for Obama, whereas private-sector union workers went 36 percent for Romney compared with 56 percent for Obama.
Breaking it down even further, the Gallup poll shows that around 3 in 10 state workers (29%) who are union members and are registered to vote support Romney, while 63 percent support Obama. And 37 percent of local government union members chose Romney versus 58 percent for Obama.
Workers who are not union members tilt toward Romney over Obama, 48-44 percent.
Gallup's conclusion: "All in all, union workers provide a substantial bloc of support for Obama's re-election efforts, although their impact on the presidential race will be limited by their size -- just about 12% of employed voters are union members -- and the fact that a sizable minority support Romney. Still, in crucial battleground states this fall, the vote and efforts of even small groups may end up making a difference."
The Gallup poll was based on telephone interviews conducted as part of Gallup Daily tracking April 11-June 5, 2012, with a random sample of 13,376 employed registered voters, aged 18 and older, living in all 50 U.S. states and the District of Columbia.
As CNSNews.com previously reported, 38 percent of voters from union households voted for Wisconsin Gov. Scott walker in his June 5 recall election.
The exit poll showing that Walker got 38 percent of the vote from people living in households with a union member was conducted by Edison Research for ABC News, CBS News, NBC News, CNN, Fox News and the Associated Press.
