I dont know of any scientific surveys... this one is thefirst one i found, a forum based self respond poll... only 20% of physicians call themselves liberals.http://forums.studentdoctor.net/showthread.php?t=500016
I'm sure other polls are more complete. But to see a repub leading among doctors seems to be expected. I would think 19 points is a skinny lead.
Most docs probably are revolted at the leftist thugs treating them like tampons who should work for free.
