U.S. Rep. Michele Bachmann's long-dormant House Tea Party Caucus is revving up again today, with the Minnesota Republican scheduled to take part in a Capitol Hill reception co-hosted by TheTeaParty.net, her office confirmed. According to a report in Roll Call, about a dozen other representatives and senators are expected at the event, which signifies that the caucus intends to stay engaged in the new 113th Congress. The Tea Party Caucus has not been much in evidence since last year, while Bachmann was defending her House seat in what turned out to be a surprisingly close challenge from DFL businessman Jim Graves. Graves has announced another run at Bachmann next year, and there are already signs that it's going to be a national rumpus. The Democratic Congressional Campaign Committee (DCCC), which sat out last year's race, pumped out a video this week chronicling the legal and ethical problems Bachmann faces from her 2012 presidential campaign. Today, the liberal Super PAC CREDO announced that it is going to make Bachmann the first target of its 2014 campaign.
