LANSING, Mich. (AP) -- The polls are open in Michigan as voters head out in the snow for the state's primary.
The race hasn't generated much interest on the Democratic side, but could prove pivotal for Republican candidates.
Polls show Mitt Romney and John McCain to be in a close race. Romney is trying to regain momentum after losses in Iowa and New Hampshire. McCain hopes to win over the state's independent voters like he did in the 2000 primary, in which he beat President Bush.
As for the Democrats, Hillary Rodham Clinton is the only big name on the ballot. John Edwards and Barack Obama pulled their names after Michigan broke national party rules by moving up its primary date.
Officials say the lack of an active Democratic contest will hurt turnout. They expect about 20 percent of registered voters to come out by the time polls close tonight at 8 p.m.
