Republican Rob Portman now picks up 44% support while his opponent, Lieutenant Governor Lee Fisher, earns the vote from 39% in the latest Rasmussen Reports statewide telephone survey of Likely Voters of Ohio’s U.S. Senate race.
Seven percent (7%) prefer some other candidate while another 11% are undecided.
The race is a bit closer than it was two weeks ago, when Portman held a 45% to 37% lead over Fisher.
The latest numbers move this race from Leans Republican to Toss-Up in the Rasmussen Reports Senate Balance of Power rankings.
In every survey conducted this year, Portman’s support has stayed in the very narrow range of 42% to 45% of the vote. Fisher’s support has ranged from 37% to 43% in that same period.
When leaners are included in the new totals, Portman still leads. With the leaners, 47% will vote for Portman and 41% for Fisher.
This is now the second Rasmussen Reports Election 2010 survey in Ohio to include leaners. Two weeks ago, Portman led Fisher 48% to 39% when leaners were included. Leaners are those who initially indicate no preference for either of the candidates but answer a follow-up question and say they are leaning towards a particular candidate.
Early in any campaign, the numbers without leaners are generally more significant. Later in a campaign, the numbers with leaners matter more. After Labor Day, Rasmussen Reports will report the numbers with leaners as the primary indicators of the campaign.
Sixty-three percent (63%) of Portman’s voters now say they are certain of how they will vote, up four points over the past two weeks. Nearly the same number of Fisher’s supporters (62%) say they are certain of their vote, down slightly from the previous survey.
The statewide survey of 750 Likely Voters in Ohio was conducted on August 30, 2010 by Rasmussen Reports. The margin of sampling error is +/- 4 percentage points with a 95% level of confidence.
