No, we've voted (R) in FDR's and Kennedy's races (and Grover Cleveland's races, but the 19th century isn't as relevant as the 20th). Dems have won without Ohio, but Reps have never accomplished the feat.
There's a first for everything, though. If Obama keeps Ohio, Romney can sweep the other swings and still win. It's unlikely, but still completely possible.
I'm just saying, if you look at the history, ever since Ohio's become a state, whichever candidate has won in that state has always gone on to win. Of course it's possible that it won't happen, but I'd bet a buck or two that it would happen again this year.
Nah, him being neck and neck with Romney is expected at this point: [link]
At this point, Romney only has one hefty state left (Texas), while Obama still has several (New York, California, more than likely Pennsylvania). We'll know for sure it's looking good or bad for a given candidate once the swings start getting called, which won't happen for another hour or two.
Based on Fox's current map, Obama's gained a few counties since 2004 but lost only one. Franklin County (where I live) hasn't been reported yet, but as the seat of the capital and home of OSU it's only going to move the votes for Obama even more.
With only 20% reporting, it's still up in the air, but I have a strong feeling that Obama's going to take Ohio.
