A recent Quinnipac University poll showed Democratic Rep. Bruce Braley leading all potential GOP challengers in the Iowa Senate race.

Democrats are also hoping to hold onto Braley’s seat in Iowa’s First Congressional District. They hold a 33 percent advantage in voter registration with 40 percent of First District voters identifying as “no party,” according to The Gazette.

Rep. Tom Latham (R) of Iowa’s Third Congressional District is retiring and Democrats are confident they will pick up his seat in November.

“It’s a solid district for us, we’ve got a good candidate, and it’s a crazy show on the Republican side so we’re hoping to pick up that seat,” said Scott Brennan, chair of the Iowa Democratic Party.

In Michigan, Democratic Rep. Gary Peters is running for Levin’s Senate seat. An EPIC-MIRA poll shows that Republican Terri Lynn is ahead of Peters with a 41-38 lead.

The retirement of Sen. Johnson could also allow the GOP to capture another Senate seat in the midterm elections. South Dakota has consistently voted for Republican presidential candidates in every election since 1964.

“We’re probably as red as any state can get,” said South Dakota Party Chair Deb Knecht. “So we’ve been building the state party from the ground up.”

Democrats are also hoping to pick up some gubernatorial seats in the Midwest.

The Democratic Governors Association has already spent $2 million on advertising in Michigan hoping to take out Gov. Rick Snyder and replace him with former Democratic Rep. Mark Schauer. Polls show Snyder is leading Schauer by 8 points.

Michigan Party Chair Lon Johnson said he is confident that Snyder will win as the state’s Democratic Party is focusing on bringing out the one million registered Democrats in the state that do not traditionally vote in non-presidential elections.

Democrats are also focusing on Wisconsin, where Gov. Scott Walker will face voters for the third time since his 2010 election. Polling shows him leading Democratic businesswoman Mary Burke by six percentage points.

Kansas Gov. Sam Brownback’s prospects for a second term have suffered due to his unpopularity among independent voters and moderate Republicans.

“We have a very good ticket and last polls that we had showed that Paul Davis was leading against Gov. Sam Brownback,” said DNC Committeewoman Teresa Krusor.

Polls show that Brownback trails Davis, a state House Democrat, by two percentage points.

“We have some very important former Republican Senate minority leaders and House minority leaders who will come out and endorse Davis against Sam Brownback,” Krusor said.
