This is based upon the following scientific methodology: bupkis.
What I did was to stare at the Google interactive Ohio returns map as the tally progressed from 13% reporting to 27% reporting, while I watched Santorum's lead grow from a few thousand to over 13,000 votes. While I stared at the map like it was iTunes Visualizer, I chanted and hummed and occasionally rolled my pointer over the counties as their returns came in and updated.
Mitt is carrying the cities and suburbs, but by small margins. Santorum is cleaning up in the countryside with large margins. As more precincts report, so far Santorum's lead has only grown.
I'm calling Ohio for Santorum.
