While Democrats believe recall elections for Governor Scott Walker, Lieutenant Governor Rebecca Kleefisch, and four Republican state senators are imminent, organizers are preparing for possible legal battles.

Earlier this week, recall groups turned in 1.9 million signatures to recall Walker and other Republicans from office. Only 540,208 signatures are needed to trigger a recall election against Walker, while organizers say more than one million were delivered to state election officials.

Despite the inevitability Democrats claim is behind their effort, attorney Jeremy Levinson say he is preparing for possible legal battles. Just what those challenges might be remains unknown though. Levinson says he expects the Walker campaign will “cook up all sorts of new-fangled legal theories about why this should be thrown out.”

The Government Accountability Board is already looking for duplicate or fake signatures, although the campaigns can also challenge any they suspect are not legitimate. Levinson admits a few problems may have “fallen through the cracks,” but nothing that will come close to compromising the hundreds of thousands of signatures necessary for a recall.

Levinson believes some Walker supporters could also step forward with claims their names were added to petitions without their knowledge. However, he also doubts those cases will be enough to stop an election.

The GAB is currently reviewing the petitions in a process that’s expected to take at least two months. The agency is planning to ask a judge to grant them more time.

With a recall election against Governor Walker likely to happen this year, Democrats are gearing up for what could be a crowded field of candidates looking to take him on. Former Dane County Executive Kathleen Falk announced Wednesday she will be a candidate, while several others have said they are considering a run.

Democratic Party of Wisconsin chairman Mike Tate says having a primary would be a good thing for the recall effort because it’s a sign of how “weak Scott Walker is electorally” and shows that more than one Democrat has done the research and thinks they have a path to victory.

A primary would add six weeks to the recall process and could result in Democrats making personal attacks on each other in hopes of winning the nomination. Tate is calling on any candidates to make sure their attention stays on Governor Walker, instead of going after each other. While the party will not be endorsing a candidate, Tate says they will call for a “clean campaign pledge” so they can enter the four week general election period ready to take on Governor Walker.

Other potential Democratic candidates include state Senators Tim Cullen (D-Janesville) and Jon Erpenbach (D-Middleton), state Representative Peter Barca (D-Kenosha), former Congressman Dave Obey, and Milwaukee Mayor Tom Barrett.

While the main focus of recall organizers was the effort to remove Governor Scott Walker from office, petition circulators were also going after signatures against Lieutenant Governor Rebecca Kleefisch. Recall groups say over 845,000 signatures were collected during that effort, making it likely her name will be on the same ballot as the governor.

Kleefisch says she’s looking forward to standing by Walker’s side on the campaign trail and focusing on what they achieved during their first year in office. She says “we’re proud of what happened over the last year and month of our time in office because we have seen tremendous reform in the state of Wisconsin and the reforms are working.”

While Kleefisch and Governor Walker will be on the ballot alone in a likely election, she expects they will campaign together. She says “we’re a team” and she stands behind the governor’s “great decisions” that lead to reforms and balancing the budget.

While several possible candidates have emerged to face Walker, there’s been little discussion of who would run against Kleefisch in a likely recall election. Still, Kleefisch she has no doubt their opponents will be “handpicked by what they believe to be out of state union bosses,” which will be a stark contrast to her and the governor.

Less than a day after more than one million petition signatures were turned in to recall Governor Scott Walker, his first possible opponent is stepping forward. Former Dane County Executive Kathleen Falk announced Wednesday that she will seek the Democratic nomination to oppose Walker in a likely recall election.

In an online message, Falk says “hope has inspired this movement, and the people of this movement inspire me.” She says a formal announcement on her candidacy will come soon.

With months of job losses, cuts to education, and what she calls an “all-out attack” on public employees, Falk says Walker’s agenda is not working. She says the state “can’t wait three more years to fix what’s wrong.”

Falk is the first Democrat to announce plans to run, although she is likely the first in what could be a crowded field of candidates. State Senator Tim Cullen (D-Janesville) has indicated he will be a candidate if an election is called, while state Senator Jon Erpenbach (D-Middleton), Assembly Democratic leader Peter Barca (D-Kenosha) and former Congressman Dave Obey are also considering their options. Milwaukee Mayor Tom Barrett, who lost to Walker in 2010, has also declined to rule out a rematch.

In a statement, Walker campaign spokeswoman Ciara Matthews called Falk the “nominee hand-picked by big-government, public employee union bosses.” Matthews says Falk’s record as Dane County executive falls in lockstep with a “Madison liberal ideology” that’s outside the mainstream of the rest of the state.
