This weekend will kick off 2 Republican campaigns, those of businessman and radio host Herman Cain and former Minnesota Governor Tim Pawlenty.

Cain will be holding a rally this Saturday in Atlanta where he will make his candidacy official. Report on Cain from Atlanta Business Chronicle:

Georgian Herman Cain plans to announce during a rally Saturday at Centennial Olympic Park he’s officially in the 2012 presidential race, according to Cain’s website.

Cain is a former Atlanta-based radio host, former chief executive of Godfather’s Pizza, and former chairman of the Federal Reserve Bank of Kansas City. He joins fellow Georgian Newt Gingrich in seeking the office.

The rally is from noon until 3 p.m.. The event is free and open to the public.

Cain’s stock has been rising recently in many GOP circles.

Tim Pawlenty plans to make his candidacy official on Monday at a Town Hall Metting in Des Moines, Iowa. Report on Pawlenty from Fox News:

He’s been all but in for months but on Monday former Minnesota Gov. Tim Pawlenty will officially announce he is a candidate for president in 2012. Pawlenty aides tell Fox News the campaign roll out will be in the form of a town hall meeting in Des Moines, Iowa. The Hawkeye State plays a crucial role in the selection process as the home of the ‘First in the Nation’ presidential caucuses and Pawlenty has been pressing the flesh there for months, hoping to raise his name recognition.

Pawlenty will head to Florida on Tuesday where he will headline a Facebook town hall. The Sunshine State is another crucial early primary test and arguably the biggest battleground swing state in the nation.

The next stop on his roll out will be in Washington D.C. on Wednesday where Pawlenty will speak at the CATO Institute. Pawlenty has long touted his “A” rating for budgetary policies from the libertarian think tank. Then he’ll make his way to New Hampshire home of the first primary of the 2012 cycle.

Pawlenty has also been trying to position himself to pick up the supporters of former Arkansas Governor Mike Huckabee following his decision to decline a 2012 run.
