Mitt Romney Leads Rick Santorum in Wisconsin Poll

After the Louisiana primary on Saturday, the procession of states that are determining which Republican will challenge President Barack Obama in November slows down with the next round coming up on April 3, when the District of Columbia, Maryland and Wisconsin have their say.

Wisconsin is the largest prize of the three with 42 delegates to the Republican convention in Tampa -- and a poll released on Friday shows Mitt Romney in solid shape to win the state.

Romney leads a Rasmussen Reports poll of likely Wisconsin Republican primary voters with 46 percent, followed by Rick Santorum with 33 percent. The other two major candidates in the race do not break single digits in the Badger State. Ron Paul takes 8 percent with Newt Gingrich right behind him with 7 percent, while 5 percent are undecided and 1 percent back other candidates.

The poll of 1,000 likely Republican primary voters was taken on March 21 and had a margin of error of +/- 3 percent.
