Yup... Maryland might be the upset this year when no one was looking.
Looks like the Obama 2012 Campaign will have to take money and resources from Ohio, PA, VA, and put into Maryland because even Maryland might be up for grabs. My gut says "no way...", but the little bit that I've been driving around the area (I70-I270 corridor, a trip into Baltimore), I've seen almost no signs/stickers in MD for either candidate.
That would be a massive upset...
This PA enthusiasm for Romney WILL spill over into Maryland.
