Of the party’s best-known possible candidates, only Mitt Romney has broad potential appeal. Large majorities have heard of four possible Republican candidates – Romney, Sarah Palin, Newt Gingrich and Ron Paul. But most who have heard of Palin and Gingrich say there is no chance they would vote for them (63% each). About as many (60%) say there is no chance they would support Paul.
By contrast, far fewer voters (44%) who have heard of Romney have ruled out voting for him, while 51% say there is at least some chance they could support the former Massachusetts governor.
