Further dems or people who vote Dems should become more focused on proximity.
It does no good spend all of your time complaining about a person you have no sway over electorally.
Guys have spent more time and energy arguing about the Junior Senators from Pennsylvania, WV, and Arizona than they have over the people they have direct access to.
