2010 Elections Poll Roundup: Good News for GOP in Wisconsin, Kentucky, and Pennsylvania

New polls show vulnerable House Democrats as well.

By + More

Republicans maintain a lead in the national generic congressional ballot, according to a new poll. And in Senate races in Illinois and Kentucky, voters say they are more likely to cast their ballots in opposition to the Obama administration than in favor of it. Other polls show first and second term House Democrats in Idaho, Indiana, and Maryland are virtually tied with their Republican challengers in districts that either backed Obama two years ago and supported George W. Bush in 2004, or supported GOP candidates in the past two presidential elections. Today's polls show that the ranks of vulnerable Democrats include Wisconsin's 18 year incumbent Sen. Russ Feingold, who is trailing by seven points, New York's first-term Rep. Scott Murphy, who is behind by 13 points, and Florida's freshman Rep. Alan Grayson, who lags behind his GOP challenger by seven points. Meanwhile, Republicans Pat Toomey and Rand Paul have opened up leads in Pennsylvania and Kentucky Senate races. Here is today's poll roundup:

National:

A Gallup Poll survey shows 48 percent of registered voters support Republican candidates while 44 percent back Democrats. Gallup found that 48 percent of Republicans say they are "very enthusiastic" about voting in the 2010 election compared to 36 percent of Democrats.

California Senate

Three-term Democratic Sen. Barbara Boxer holds a narrow 48 percent to 44 percent lead over Republican Carly Fiorina, with a 3 percent margin of error, according to a Pulse Opinion Research poll for Fox News. However, 50 percent say they disapprove of the job Boxer is doing in the Senate while 41 percent approve. 

Connecticut Senate

Democratic state Attorney General Richard Blumenthal leads Republican Linda McMahon by double digits, according to two new polls. A Pulse Opinion Research survey for Fox News shows Blumenthal leading the former World Wrestling Entertainment CEO 53 percent to 42 percent among likely voters. He also has the edge in terms of favorability, 53 percent to 42 percent. The poll also found that 44 percent say they would rather support an "outsider who wants to shake things up" while 41 percent prefer "an insider who knows how to get things done." A Quinnipiac University poll shows Blumenthal leading McMahon by 12 points, 54 percent to 42 percent among likely voters. More women say they support Blumenthal over McMahon 61 percent to 35 percent, while men were split pretty evenly between the two candidates. 

Florida's 8th House District

First-term Democrat Grayson trails Republican and former state Sen. Daniel Webster by seven points, according to a Sunshine State News poll. Webster holds a 48 percent to 41 percent lead among likely voters in the Orlando area district, which supported Obama in 2008 but backed Bush in 2004.

Both candidates are split pretty evenly among independent voters, 36 percent for Minnick and 37 percent for Labrador, with 16 percent of independents undecided.

Illinois Senate

Republican lawmaker Mark Kirk and Democratic state Treasurer Alexi Giannoulias are in a statistical dead heat in the race for Obama's old Senate seat, according to a Pulse Opinion Research poll for Fox News. Kirk edges Giannoulias 43 percent to 41 percent among likely voters with a 3 percent margin of error. The poll indicates that 44 percent say their Senate vote will show their opposition to the Obama administration's policies while 40 percent say their vote will express support. 

Indiana's 2nd House District

Two-term Democratic Rep. Joe Donnelly and Republican Jackie Walorski are in a statistical tie, according to a Epic-MRA poll released today. Walorski edges Donnelly 48 percent to 43 percent among likely voters, with a 4.9 percent margin of error. Obama's favorability rating in the state is 38 percent. The South Bend area district backed Obama in 2008 but supported Bush in 2004.
