The taller candidate tends to win presidential elections. This could bode well for Romney or Pawlenty (both reportedly 6'2" or taller, compared to Obama at 6'1").
How would height affect a female candidate's chances? Would a six foot tall woman appear stronger... or too strong? Would a short woman emphasize cultural worries about paternal vs. maternal presidential instincts?
I long for the day that we have a woman in the oval office. I don't think I'll ever see it happen, but I do long for it. I do not long for the likely onslaught of "presidential tampon" humor.
