Political panel: 2012 candidates to spend Labor Day campaigning

Candidates and potential candidates for the 2012 GOP nomination have been busy campaigning this weekend and they will have no rest this Labor Day as they try to rally supporters in a host of events across the country.

Following a appearance in Iowa on Saturday where she spoke to a group of around 2,000 people who had gathered hoping that she'd  make some indication as to whether or not she'd run for the nomination, Sarah Palin will be in New Hampshire today for a Tea Party event.

Meanwhile, Rick Perry, Mitt Romney and Michelle Bachmann will be at a forum in South Carolina event hosted by Senator Jim DeMint, a leader in the new conservative grassroots movement that includes so-called tea partiers.

Roll Call politics writer Shira Toeplitz and Politico senior political reporter Ben Smith explain what Palin's weekend event could signal about her intentions to run and whether Sen. DeMint's forum will push Perry to the front of the candidate pack.
