As Mr. Romney and Mr. Santorum traded a new round of sharp charges in Michigan on Saturday, some Republican leaders expressed concern about the effects of a prolonged and nasty primary fight.
“The general election prospects for Republicans certainly would be better served if more focus was spent on Obama’s policies and the failures of those policies,” said Haley Barbour, the former governor of Mississippi and a longtime party leader. “There’s still time for that, but it would improve our prospects greatly.”
Mr. Barbour was speaking at the winter meeting of the National Governors Association in Washington, where the presidential race and the alarm over its intense negativity were central topics.
