The latest Ohio Republican presidential poll shows a toss-up race between Rick Santorum and Mitt Romney heading into the final weekend before the primary.
The Quinnipiac University poll Friday gave the former Pennsylvania senator 35 percent to 31 for former Massachusetts Gov. Romney. The four-point lead is within the poll's margin of error, and tighter than a Quinnipiac poll released Monday that gave Santorum a 36-29 lead.
Both candidates have multiple Ohio stops this weekend.
The poll also found about a third of the voters might change their minds by March 6.
Former House speaker Newt Gingrich was third at 17 percent, with Texas Rep. Ron Paul at 12 percent. The Feb. 29-March 1 telephone survey interviewed 517 likely Republican voters, with a margin of error of 4.3 points.
