Tim Pawlenty ends 2012 White House bid

CBS News political correspondent Jan Crawford reports on how Republican presidential candidates are struggling to get the attention that Sarah Palin gets.

ST. PAUL, Minn. — Former Minnesota Gov. Tim Pawlenty is dropping out of the race for the Republican presidential nomination.

Pawlenty told supporters on a conference call Sunday morning that he would announce on ABC's "This Week" that he was ending his campaign after a disappointing finish in the Iowa straw poll on Saturday.

The poll was a test of organizational strength and popularity in the state whose caucuses lead off the Republican nomination fight.

Pawlenty had struggled to gain traction in Iowa, a state he had said he must win, after laying the groundwork for a campaign for nearly two years.

He's been eclipsed in polls in recent months by his Minnesota rival, congresswoman Michele Bachmann. She won the straw poll on Saturday.
