MADISON, Wis. (AP) -- Republicans who control the state Legislature have amassed a huge cash advantage over Democrats as the GOP works to retain and increase its hold on the Assembly and Senate in 2014.

Legislative Republicans collectively raised $1 million through the end of June, compared with just $411,000 raised by their Democratic colleagues, according to an analysis of the fundraising released Wednesday by the Wisconsin Democracy Campaign.

Republicans also have a fundraising advantage in campaign committees, with $363,000 cash on hand in July compared with just $143,000 for Democrats. Individual Republican lawmakers combined had $2.5 million on hand compared with $817,000 for Democrats.

The higher numbers aren't a total surprise given that there are more Republicans than Democrats in the Legislature. Republicans currently have a 60-39 majority in the Assembly and 18-15 in the Senate.

Even so, the figures show that Democrats will have to come from behind financially when trying to knock off Republicans in legislative districts that GOP lawmakers drew to be friendlier to their side.

"Obviously they're out-fundraising us but we feel if we can keep it close, keep it competitive, we're going to have great candidates to run," said Wisconsin Democratic Party spokeswoman Melissa Baldauff.

In the Senate, 17 of 33 lawmakers are up for election in 2014. Of those, 11 are Republicans and seven are Democrats. All 99 seats in the Assembly are up.

Most of the hottest races are expected to be in the Senate, in large part because Republican control is more narrow and they have more seats to defend. Democrats are also widely expected to have a hard time holding a seat in Racine, currently held by John Lehman, given new boundaries that favor Republicans. Former Sen. Van Wanggaard, whom Lehman beat in a 2012 recall to win the seat, has already announced his candidacy. No Democrat has gotten into the race.

Republicans expect to win back Lehman's seat and are also eying a possible pickup in the western Wisconsin seat held by Democratic Sen. Kathleen Vinehout, said Wisconsin Republican Party executive director Joe Fadness.

"The bottom line is the Democratic Party right now is in disarray," Fadness said, adding that the Republican Party is working in the off-year to raise money, open field offices, and register voters.

Democrats are targeting six Republican Senate seats, although they only have a candidate for one of them. Baldauff said she expected more candidates to start announcing in the next couple weeks.

Two of the seats targeted by Democrats involve the longest-serving Republican in the Legislature, Senate President Mike Ellis, and moderate Republican Sen. Dale Schultz.

Ellis, a 31-year Senate veteran representing a northeastern district that includes Appleton, is facing a Democratic challenge for the first time since 1998. Rep. Penny Bernard Schaber announced last month that she was taking on Ellis.

"It's kind of a crazy thing to do, but I'm ready for it," Schaber said on the day she announced her run.

The fundraising reports show Ellis with a $142,000 balance compared with $27,000 for Schaber.

Ellis, who describes himself as a "moderate to conservative but independent voice," has angered both Republicans and Democrats in recent years. He was a key negotiator with Gov. Scott Walker over his voucher school expansion proposal, creating a compromise that ultimately angered people on both sides of the issue.

There has been talk of Ellis even facing a primary challenge from a more conservative Republican, but none has emerged.

Schultz does have a Republican primary challenger.

A well-known moderate, Schultz has angered more conservative Republicans with his outspoken opposition, and votes against, Walker's bill effectively ending collective bargaining for public workers in 2011, a proposal loosening environmental regulations to make it easier to open an iron ore mine in northern Wisconsin, and Walker's state budget this year.

Schultz's Republican primary challenger, Rep. Howard Marklein, raised $116,000 in the first half of the year compared with just $684 for Schultz. Schultz, a 22-year Senate veteran and former majority leader, has repeatedly said it's too early to be focused on re-election and he will make that decision closer to the end of the year.
