I've been casting my vote against politicians since I first started voting in '76. Don't recall voting FOR them. 
After Ronald Reagan, it was instinctive to support GHWB.
At the time, his "read my lips...." broken promise didn't seem like such a big deal, personally.
After 8 years of the Clintons, GWB was a breath of fresh air. I avidly supported him and participated...took hundreds of photos at VP Gore's residence at the Naval Observatory entrance as well as the demonstrations at the Supreme Court.
First candidate I was ambivalent about...John McCain. Definitely voted against the Manchurian.
Same as with Romney.
Yep...those 'principled' Conservatives sure showed us what happens when they don't approve of a candidate's [religious] pedigree.
Now they're trying the same thing over this bullsh*t faux pas in Helsinki.
We should all be concerned about November. I said in here over a year ago that the DEMS/MSM/SOCMEDIA are going to whip everybody up like never before to get off their asses to vote.
I hope and pray the President's megaphone is louder.
