The pro-Rick Santorum super PAC has widened its reach, buying ad time in the Super Tuesday state of Ohio with ads beginning today. The "Red, White, and Blue Fund" made a $257,000 buy in the state and the ads will run through Wednesday.

It's a new ad but the group has yet to release it, although it is expected to do so Friday. The largest buys are in the Columbus and Cincinnati areas, with $53,500 spent in Columbus and $56,000 in Cincinnati. There are smaller air purchases in Dayton and Toledo, and a Fox News buy in the Cleveland area.

It already has a negative ad running in Michigan that compares Mitt Romney to President Obama and it also ran a positive one in the state. With the two ads, the super PAC spent $1.3 million in Romney's home state.

An NBC-Marist Michigan poll this week showed Romney with 37 percent and Santorum 35 percent support in Michigan. The state votes Tuesday, along with Arizona.

The pro-Mitt Romney super PAC is already on the air in Ohio with a negative ad against Santorum that calls him a "big spender" and a "Washington insider."
