LANSING -- It's the flourish before the final weekend.
GOP presidential candidate Mitt Romney urged support from the Detroit Economic Club at Ford Field on Friday morning. He refocused his message on the economy, pledging to reduce income tax rates by 20 percent, though independent analysis has shown that could increase the already sizeable deficit.
He also pledged to lower corporate taxes.
"Second, I'm gonna make our business taxation -- the C corporation taxation -- competitive globally," he said. "I'm gonna reduce the corporate tax rate to 25 percent from the current 35 percent."
And Romney took a question about who has the best shot at beating President Obama.
"I not only think I have the best chance, I think I have the only chance," he responded.
At Chisholm Hills Golf Club in Lansing, Republicans prepped for Romney's visit there Saturday -- hoping they can help his cause.
"The important thing is finding somebody who can win and beat our current president," said Ingham County Republicans leader Norm Shinkle. "And I personally think Mitt Romney has the best resume and charisma to do that."
Rick Santorum's campaign, meanwhile, was hoping to get a boost from a state-wide bus tour of social conservatives.
"People are looking for the authentic, genuine person that can lead this country and really is pro-life," said Marilyn Musgrave.
They stopped at the Capitol on Friday to drum up votes for Santorum and his anti-abortion credentials.
This as Santorum lashed out at Romney in one ad as a hypocrite, who himself supported earmarks in the past. After all, time is running out to state their case before Tuesday's primary.
The latest polls out Friday show Romney with a 5 percent to 8 percent lead in the polls.
Ron Paul will be campaigning in the state Monday, including at Michigan State University in the evening.
Newt Gingrich has said he will not campaign in the state.
