Right or wrong, people judge other people, perhaps subconsciously even, by their appearance, or they are affected by one's appearance when forming an opinion about someone.
I'd like to know, to quantify it, but Marsha Blackburns attractive face and feminine demeanor would be worth a LOT of votes when people--male or female--see her and then see pictures of Huma-munching Hillary or Fauxcohantas. Two screeching hysterical old cones not aging well at all, juxtaposed with Marsha? Like it or not, that would be worth a lot.
point noted, Marsha's easy on the eyes and will help rake in more female voters nation-wide, but Trump doesn't particularly need help to win Tennessee.
How about Iowa's Joni Ernst?. She could also help Donald tear away female voters from Hitlery, but also in a much needed midwest swing-state to boot!
