Mitt Romney no doubt has the most politically problematic record on health care of any of the Republican candidates, but as the campaign progresses, Tim Pawlenty will face questions from conservatives about his support for the expansion of the State Children’s Health Insurance Program.

Back in 2007, the newly-elected Democratic majority was in a pitched battle with the Bush White House over the renewal and expansion of SCHIP. Democrats saw it as a down payment on universal health care, but President Bush eventually vetoed the legislation, which raised tobacco taxes and expanded coverage to children from families with household incomes of up to $82,600.
