Tim Pawlenty and Mitt Romney had easy smiles during a joint appearance in Bloomington Friday night, but their pleasantries hid a coming deep rivalry -- and some unkind past words.
Pawlenty, Minnesota's governor, and Romney, Massachusetts' former governor, are the only Republicans who appear to be openly campaigning to oust President Obama.
In recent months, Pawlenty and Romney, a 2008 presidential contender, have crisscrossed the country giving speeches, helping 2010 candidates and raising money to dole out to others and fund their politicking.
That alone makes their twin speeches at the Freedom Foundation of Minnesota's fundraiser before about 400 donors notable.
In other forums, the two have sniped at each other.
For more than a year, Pawlenty, who supported Sen. John McCain's 2008 presidential bid, has taken shots at a Romney signature -- the Massachusetts health law that requires individuals to carry health insurance. Like others, Pawlenty likens that law to the federal health care overhaul.
"Looking at the Massachusetts experience, it would not be one I would want for the country to follow any further," Pawlenty said in New Hampshire last month.
Romney hit back. "Facts are stubborn things," he said on CNN last year. He said a study found the plan's cost "well within the original forecast" years after it became law.
