Mitt’s main argument to GOP voters is, “You may not like me much, but I’m the best one to beat Obama.” Really? That’s not what the latest CNN poll of registered voters shows. Although bear in mind that polls of registered voters aren’t as reliable as polls of likely voters.
The CNN poll shows Obama beating Mitt 54% to 43%. Obama beats Santorum 55% to 42%, so not much difference between Mitt and Santorum as the GOP nominee.
Mitt is also like Santorum in having his favorables/unfavorables upside down. Obama’s are positive — 56%/42%. Mitt’s are 37%/49%, and Santorum’s are 35%/42%. You don’t win when your favorables are in negative territory.
