Last night - I had to yell at my mother

Last night, I had to yell at my own mother. I was talking to my dad in the ultra-conservative Shenandoah Valley of Virginia and he tells me that my mother is refusing to vote in this year's presidential election. So he puts her on the phone, and though I was losing my voice as a result of this flu/head cold I've had for almost two weeks now, I proceeded to urgently explain the need for her to vote. It seems that though she doesn't believe in McCain, she is unsure about Obama for president. She actually brought up a fear that he'd be assassinated in the first 6 months. She said, "you don't know - you didn't live through Kennedy's assassination - that was a horrible experience." I then explained that EVERY president runs that risk and security measures are far better today than they were in 1963. I continued to reason that if it were that easy, one of these dumb rednecks would've offed Bill Clinton by now - they STILL blame him for everything under the sun.
The thing that concerns me about this, "I'd never vote for McCain, but I don't know about Obama, so I'm not voting" phenomena is that I only ever hear this from non-Republicans. So essentially what this means is that the Republicans are gonna show up and vote - no problem, but what of these McCain-haters that won't show up and vote against him?! It concerns me because this could be a much closer race than it appears. And all the 'Pubs need is to have the election close enough so that they can implement the deceptive election-rigging program they've used for the last 8 years. And the election goes to the bitter, old guy who gave up his scruples to be the president ... and Tits McPalin - the void - who will probably take over in the near future after he drops dead.
If anyone reading this knows one of these McCain-hating, non-voters - please ... I beg of you - encourage them to vote!
