Not good advice in my opinion. IMHO, and speaking not only as being married to a woman in the medical field but as the father of a 12 year old who had heart surgery when she was 10, politics has nothing to do with medicine. When someone's cutting on a loved one, you want the absolute most competent professional present, and politics doesn't make good doctors.
I know full good and well that the surgeon who did my daughter's operation is a flaming lib, but I don't give a damn. He's without a doubt the best surgeon in his field, in this area, and I considered it a huge boon and favor that he took the time to perform a fairly routine repair, when most of his work is typically much more lucrative pedi-transplants.
There are exceptions, of course. This situation would certainly put politics at the bottom of my list. But when someone is in a scientific career and they are in the "guns are bad" group, then the linearity of their thought process probably ought to be considered. FRegards
