The state and federal governments paid substantial money to train this guy as a physician. Rather than repay that debt to society, he chooses to go into politics. 

We've seen this act before, and it never ends well. If he is a capable person who can be trained, he should be a good physician who wouldn't want to leave a field in which he excels. If he's not capable, I can see why he wants to change fields, but why would we vote for someone who isn't capable?
