A comment like that, from someone who had five deferments, usually voters frown upon that. For example, many of the same R voters despise Kaepernick for kneeling during the anthem. Cole went on a whole thing about it last week. "You don't disrespect the flag" and all that. Trump says he likes people who don't get caught, seems like a pretty clear slight to POW's. Like there is something weak about that.
And again, during the primaries. Didn't have the "well Clinton sucks" excuse then.
