CASS COUNTY — Local voters say the economy, health care and values were the key issues that drove them to the polls. Turnout was estimated to be 17 percent in Berrien County and 20 percent in Cass County.

Preliminary results show Sen. John McCain won Berrien and Cass counties, but Mitt Romney did much better statewide. He won in more populated areas including Grand Rapids and the Detroit suburbs and that was the difference.

"Tonight we are celebrating in Michigan, I gotta tell you that," Romney told supporters in Southfield, Mich. "But guess what they're doing in Washington. They're worrying. Because they realize, the lobbyists and the politicians realize, that America now understands that Washington is broken and we're going to do something about it."

Sen. John McCain finished second and Former Arkansas Governor Mike Huckabee finished third. Both men spent Tuesday night in South Carolina, as they prepare for the next primary.

"For a minute there in New Hampshire, I thought this campaign might be getting easier," Sen. McCain told supporters in Charleston, SC. "But you know what, we've gotten pretty good at doing things the hard way, too, and I think we've shown them we don't mind a fight and we're in it."

"It looks like I won Iowa, John McCain won New Hampshire, Mitt Romney won Michigan, but ladies and gentlemen, we're going to win South Carolina," Mike Huckabee said as he spoke to supporters in Lexington, SC.

Exit polls showed the economy was the key issue for voters statewide. They also showed that Independents and Democrats did crossover to vote in the Republican primary, but not in large numbers.

"They're all saying pretty much the same thing, 'There's not a big change and so what I want, I need someone I can trust in the office,'" said Anthony Habra, an Independent voter in Cassopolis.

On the Democratic side, Sen. Hillary Clinton, D-New York, was the only major candidate on the ballot. Sen. Barack Obama, D-Illinois, and John Edwards pulled their names off of the ballot, because Michigan violated party rules by moving its primary to January.

Democratic voters who supported those candidates were urged to vote uncommitted. Analysts said the uncommitted line did pretty well, which could cause problems for Clinton in November, if she should win the nomination.
