Sen. Hillary Rodham Clinton's name was the only top Democratic choice on ballots in the Michigan primary Tuesday as two Republican contenders were locked in a tight race.

Sen. Barack Obama (D-Ill.) and former Sen. John Edwards (D-N.C.) pulled their names from the race after the state ignored warnings from the Democratic National Party and moved up its primary date. The DNC stripped Michigan of its delegates in response.Obama urged supporters to mark the word "uncommitted" on their ballots, since Clinton's name is the only one left among Democrats.

On Monday, Clinton tried to get past a dustup after the Obama campaign accused her of ignoring Dr. Martin Luther King Jr.'s legacy. Clinton was quoted as saying Dr. King?s dream was realized when President Lyndon Johnson signed the Civil Rights Act of 1964. Obama took issue with the remark. Clinton later claimed Obama was distorting her statement.

"Who would ever dream that we'd see an African-American and woman running for president?" Clinton said while speaking to union workers in Manhattan Monday.Meanwhile, polls show former Gov. Mitt Romney (R-Mass.) and Sen. John McCain (R-Ariz.) running neck and neck in Michigan. McCain won the state's primary eight years ago, while Romney's father served as governor there. News 12 political analyst Mike Edelman believes McCain will come out on top over former New York City Mayor Rudy Giuliani and Romney.

"I think by default ? McCain offends the least amount of people. He has the most conservative positions," Edelman said.
