have you seen the actual numbers?
Obama won all of the urban counties, which tend to be more Democratic than the rural areas, by a 12 point lead, but statewide lost by 10 points.
Two things to remember: this effect was most largely seen in Republican strongholds where it is doubtful that there was a sudden revolution to support someone they've spent years being told to hate and where Democrats are not very prevalent in the first place.
Also, the number of Democratic voters yesterday was more than twice what was expected.
Total votes for both Hillary and Obama in Ohio= 2,186,831
Total votes for both Mccain and Huckabee in Ohio= 961,837
In the 2004 Ohio Primaries, Kerry & Edwards totaled 1,048,694.
In the 2000 Ohio Primaries, 961,999 total for Gore & Bradley.
I do agree that for several reasons, this year had more allure for Democratic voters, and first time primary voters (such as myself), and far less for Republicans, so I am not trying to say it was all shenanigans, but it sure looks like a lot of it may have been to me. It's really hard to say until November.
Also, the Republican numbers went down:
http://www.thegreenpapers.com/PCC/OH-R.htmlin 2000, there were almost 1.4 million Republican voters in their primary.
http://www.thegreenpapers.com/P04/OH-R.phtmlIn '04 there were 800,000, but they had an incumbent.
So in keeping with the idea that the number of voters should go up with population increase as well as through GOTV efforts, you'd think they'd at least be in a similar range. Maybe not though. I agree that their side was pretty much already decided at this point, so maybe that discouraged them. I'm not saying all, or even a majority of Hillary's votes were from Republicans, but they sure seemed to take her over the top, not only in Republican areas, but to the point that counties ran out of ballots.
