The Rasmussen Reports daily Presidential Tracking Poll for Wednesday shows Mitt Romney attracting support from 47% of voters nationwide, while President Obama earns the vote from 43%. Four percent (4%) prefer some other candidate, and seven percent (7%) are undecided. Romney’s lead is a bit larger whenleaners are included.

In Ohio, the candidates are tied at 45% each. Ohio remains one of 12 states with 156 Electoral Voters that are either Toss-Ups or Leaners in the Rasmussen Reports Electoral College Projections.

Initial voter reaction to Romney’s new running mate Paul Ryan is modestly positive. Fifty percent (50%) have a favorable opinion of him. He is seen as politically conservative by seven-out-of-10 voters which places him as far to the right as Obama is to the political left. Political analyst Michael Barone notes that the selection of Ryan puts the nation’s entitlement crisis at the center of this year’s campaign.
