With polls showing President Barack Obama opening a lead over Romney following the Democratic National Convention in Charlotte, N.C., Republicans on Capitol Hill are saying Romney should either offer more details or come up with a bold proposal, such as the "no new taxes" pledge then-Vice President George H.W. Bush offered when he was the GOP nominee in 1988, The Hill reported Saturday.
"Papa Bush was down after the Democratic convention in 1988, people worried he couldn't come back and then he made his 'read my lips, no new taxes' pledge," said a U.S. senator who requested anonymity.
Another senator, who also requested anonymity, said the campaign has blurred Romney's image as a problem solver.
"My advice is don't try to turn him into something he's not," said the senator. "You're never going to turn him into a teddy bear."
One lawmaker said Romney needs to be more specific with voters about his proposals.
"If you're going to bring it to the American people, you've got to show details," the lawmaker said.
The Romney campaign did not comment for the article, The Hill said.
Romney was not on the campaign trail Saturday. He is scheduled to campaign in Colorado Sunday.
Saturday's Gallup Daily tracking poll showed Obama ahead of Romney 49-45.
