Some GOP senators are worried that Romney has yet to give voters a clear vision of what to expect if he is to become president.

Another GOP lawmaker said the aura Romney’s advisers are trying to create around the candidate has muddled the most compelling rationale for his candidacy: he is a no-nonsense problem-solver who can turn the economy around.

“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.

“He needs to say if you elect me, this is what you’re going to get, someone who’s going to bring common sense to the White House,” he said.
