Let the games begin! Mitt Romney tonight won the Republican primary in Michigan pretty convincingly. He garnered 39% of the vote compared to John McCain’s 30%.

Mitt Romney scored his first major primary victory Tuesday, a desperately needed win in his native Michigan that gave his weakened presidential candidacy new life. It set the stage for a wide-open Republican showdown in South Carolina in just four days.

Three GOP candidates now have won in the first four states to vote in the 2008 primary season, roiling a nomination fight that lacks a clear favorite as the race moves south for the first time.

The former Massachusetts governor defeated John McCain, the Arizona senator who was hoping that independents and Democrats would join Republicans to help him repeat his 2000 triumph here. Mike Huckabee, the former Arkansas governor, trailed in third, and former Tennessee Sen. Fred Thompson is making a last stand in South Carolina.

“It’s a victory of optimism over Washington-style pessimism,” Romney said in an Associated Press telephone interview from Southfield, Mich., echoing his campaign speeches and taking a poke at McCain, the four-term senator he beat. “Now on to South Carolina, Nevada, Florida.”

I’m not convinced either McCain or Romney should be the leader of the free world, let alone ANY democratic candidate. If Thompson wins South Carolina and Guiliani wins Florida, we may be in for some fun in the coming weeks.
