Cop and Doc Polling

I would love to see a poll done of police officers showing 2008 Presidential vote vs. current party preference or at least Presidential approval. For that matter, I'd love to see the same breakout for medical professionals as well. If they're miffed, I don't expect that to be a long-term trend - most people get over this kind of thing eventually, moving on to greater concerns - but there's some percentage that won't. There's a subset of that group that voted for Obama and likely won't again. How many people could that possibly be?

Poll cops, docs and their extended families. How many 1000s (10s of 1000s??) could he have negatively persuaded?
