NOVI, Mich. (AP) -- Mitt Romney is calling Republican rival Rick
Santorum "an economic lightweight" as the candidates make
last-minute pitches to voters in Tuesday's Michigan and Arizona
Romney says voters recognize that November's election will
"come down to a race about the economy," and says Santorum is not
the right candidate to challenge President Barack Obama.
Appearing on Fox News Channel, Romney said he doesn't think
Republicans "want to nominate an economic lightweight to go up
against the president, who also is an economic lightweight."
Romney also objected to Santorum's use of "robocalls"
encouraging Democrats to vote in Michigan's Republican contest.
Romney called it a "terrible, dirty trick."
