With days to go before the polls open on Super Tuesday, Republican voters in Ohio are not very sure of who they want to nominate to take on Barack Obama.
According to a Rasmussen poll released Friday, only 57 percent of likely Republican voters are certain of who they will pick Tuesday, while 35 percent say they are open to suggestions.
A Quinnpiac poll also released Friday tells the same story. According to that poll, 34 percent of voters who named a favorite candidate said they still might change their minds by Tuesday.
Ohio's population of undecided voters represents a large unknown. By comparison, polls ahead of the Michigan primary and Iowa caucuses, two hotly contested nominating contests, showed significantly smaller percentages of undecided voters.
Public Policy Polling released a poll the day before the Michigan primary showing 73 percent of voters strongly supported their candidate. In the end, only 40,000 votes separated Rick Santorum and Mitt Romney, and the two split Michigan's 14 congressional districts.
In Iowa, where the nominee was eventually determined by only 35 votes, the story was similar. The last PPP poll released before caucusing began on Jan. 3 showed 76 percent of voters were certain about who they would vote for.
Ohio may prove to be a tight contest on Tuesday. Rasmussen's poll has Santorum up two points on Romney. Quinnipiac's poll has Santorum's lead at five points, but those numbers could change with such high percentages of uncertain voters ahead of Tuesday.
