Why is everyone allowed to vote?

You can say it’d be a slippery slope, but in all seriousness, people should be TESTED before they can vote. This is why:

Yesterday I was having a conversation with one of the girls here in the office. She’s 20 years old, and dumb as a brick. She said she was voting for McCain, and I asked her why.

“Obama is for abortion.”
What do you mean Obama is for abortion?
“Obama wants women to get abortions!”
No, he wants a woman to have a choice. Wouldn’t you rather have a choice than have some people you’ve never met say you MUST bear a child for 9 months and then spend 5–20 hours in painful childbirth, and then you have to pay out of pocket… because those same people don’t have insurance because there’s no national insurance plan?
”...and it’s Clinton’s fault we got bombed on 9/11!!”
We didn’t get bombed on 9/11. And Bush’s family is the one that’s been in bed with the Bin Ladens for years.

What kills me is, she got the bit about Clinton from Michael Moore’s documentary. Um, huh? Michael Moore’s documentary pointed the finger at the Bush administration! And if this idiot in my office can pull this shit out of her ass, who’s to say how many others are doing the same thing? Why the hell are people allowed to vote who don’t know shit about SHIT?! My best friend is voting McCain, but her dad is one of those rich business owners that whose wealth will be protected while the struggling working class keeps him rich. So I get her selfish vote, sort of. But when this idiot ends her argument with, “PLUS, We need a woman for President!” and I realize instantly with horror that she wants SARAH FREAKING PALIN to run the country, I want to throw up.

I can’t work a nuclear reactor, so you know what? I don’t apply for jobs at a nuclear power plant!

I can’t even rant coherently anymore, I’m so frustrated.
