The presidential contest goes national

WASHINGTON (CNN) - The presidential race is definitely national now, as the remaining candidates fan out today in five states.

Hillary Clinton and Barack Obama are safely on opposite sides of the country. He hits the campaign trail in Nevada and she spends time at a Martin Luther King Day event in New York after a weekend filled with fallout over her comments on the slain civil rights leader and a heated back-and-forth with the Obama campaign.

Meanwhile, the top three Republicans in the Michigan primary contest spend the day in much closer proximity, brushing past one another as they race across the state in the final hours before Tuesday's vote. Mike Huckabee and Mitt Romney – who spent Sunday tangling over taxes – visit the Detroit Auto Show within a few short hours of each other, and John McCain hits five cities in a bid to get an edge, after two polls showed a tight race in Michigan.

In the state’s Democratic primary race – where most of the field doesn’t even appear on the ballot – Hillary Clinton currently leads “uncommitted,” 56 percent to 30 percent in the Detroit Free Press poll released this weekend. Supporters of John Edwards and Barack Obama have been urged to vote “uncommitted”– a move that could create an unexpected headache for the Clinton campaign.

The question of the day: Which will be the bigger factor in tomorrow’s Michigan vote – evangelicals mobilizing for Huckabee, or the expected deluge of crossover voters?
