EMILY's List is not the only major national group involved in the race: Unions including the AFL-CIO, AFSCME and SEIU have joined together to create the We Are Wisconsin PAC, the League of Conservation Voters and Democracy for America are also spending there, and the Democratic Legislative Campaign Committee on Wednesday became the first national group to run television ads. On the right, the Club for Growth and Americans for Prosperity have both gotten involved. The groups will likely spend millions of dollars combined on the campaign.

The February fight over unions fired up a depressed Democratic base, and Democrats in Wisconsin and D.C. are hoping they can keep the energy up with these recalls, and possibly recall Walker if they are successful. They also see it as an opportunity to paint a contrast between their policy vision and Republicans’ and to avoid a repeat of the 2010 elections, which were seen as a referendum on Obama rather than a choice between the parties.
