A poll from Rasmussen Reports released on Monday finds that Republican presidential hopefuls Rick Santorum and Mitt Romney are in a close battle in Ohio, which holds its primary -- with 66 delegates on the line -- on Tuesday.

Santorum takes 32 percent of the poll of likely primary voters while Romney is right behind him with 31 percent. Newt Gingrich and Ron Paul are knotted together in a tie for distant third with 13 percent each. While 6 percent remain undecided, 3 percent say they will back other candidates in the race.

The poll of 750 likely Ohio Republican primary voters was taken on March 4 and had a margin of error of +/- 4 percent.
