"You just had Paul Ryan on ["Face the Nation"] he's 42. Marco Rubio, Scott Walker, Chris Christie, Nikki Haley, I mean it's a young party. But it just kind of shows you we've done a really lousy job of branding and marketing who we are."

Meantime, the report also lays out proposed fixes to the party's presidential nomination process, arguing that there are too many debates and that the primary calendar is simply too long.

"The report finds it 'advantageous to move quickly into the general election phase of the campaign, allowing the nominee to spend general election money sooner," Priebus will say today, according to his prepared remarks.

"I'm calling for a convention in June or July," Preibus said on "Face the Nation."

"No more August conventions," he added.

Priebus said an earlier convention will help the eventual nominee go in stronger and come out with more time to try to win the general election.

"One of the reasons why Mitt Romney was a sitting duck for two months over the summer is under the campaign finance law - he couldn't use money he had already raised until after he received the nomination for president in August. "

"I believe that our primary process is way too long. I think our calendar needs to be looked at. I think our debate calendar needs to be shrunk. I think we had way too many debates with our candidates slicing and dicing each other and I think they had to wait too long to get to the convention," Priebus said.

"I would do one a month, this is me talking now. I would do one a month. I would have more say over the moderators, more say over the debate partners. I would limit the debate to a reasonable amount. I don't know, maybe seven or eight, but not 23, Bob. That's ridiculous."
