A new Rasmussen poll shows Republican Senate candidate Josh Mandel has tied incumbent Democratic senator Sherrod Brown with 43 percent support apiece. That's a change from a poll in early February, when Brown held a four-point lead over Mandel in a head-to-head match-up. Here's more from Rasmussen:
In early February, Brown held a slight 44% to 40% advantage over Mandel in Rasmussen Reports’ first look at this race. Mandel captured 63% of the vote in a five-candidate field in the March 6 primary. Typically, a candidate receives a bounce in support following a primary win. Popular freshman Senator Marco Rubio of Florida also has campaigned for Mandel in the state. But Mandel is also under considerable fire from Brown's supporters and some in the media for the truthfulness of an ad he's running claiming his Democratic opponent is responsible for sending Ohio jobs to China.
Earlier this month, Mandel scored a big endorsement from Florida senator Marco Rubio, Rubio's first endorsement of the 2012 cycle.
