Tim Pawlenty, Michele Bachmann, Rick Santorum, Mitt Romney and Sarah Palin have been mentioned as potential candidates.
Three years ago, GOP candidates were all but piling on each other to announce their candidacy for the Republican nomination for president. This year, not so much.
"No one wants to be first. You want to be a contender, but you don't want to be viewed as the establishment candidate, because we saw that was a curse last cycle (in 2010) in Republican primaries," said Nathan Gonzales, political editor for the nonpartisan Rothenberg Political Report. "A lot of people who were deemed the initial front-runners with establishment support were then immediately met with opposition, because people wanted an outsider."
And potential candidates are leery of getting out front too early and becoming the target of attacks.
