DETROIT (WWJ) - On the eve of the Michigan Republican presidential primary, metro Detroiters are telling WWJ Newsradio 950 what the candidates should be talking about.

On the street, people are saying they are concerned about “jobs mainly, unemployment and the economy.”

Meanwhile, Mitt Romney and Rick Santorum are very close in the polls, with some polls showing Romney with a slight edge in Michigan.

Chief political strategist for the Potomac Research Group Greg Valliere said the outcome of the Republican primary in Michigan is tough to predict because it’s a state that allows party crossover voting in primaries. If Democrats vote, that could make a difference.
