Dude, McCain is batshit crazy
To reiterate a point from the weekend, the fact that Sarah Palin shouldn't be one heartbeat from leading the free world is obvious, but beside the point. The problem here is that John McCain's judgment is so comically flawed, the prospect of his presidency is starting to become quite literally frightening.
Even cursory vetting would have turned up some of these basic details of Palin's record. Indeed, her career in public office is so brief, this should have been extremely easy for even incompetent researchers. McCain, one assumes, would have demanded extensive background information before making a decision of this magnitude. Except, he didn't.
So, what are we left with here? John McCain met Sarah Palin in person once, for 15 minutes. Months later, he then talked to her on the phone for five minutes. Four days later, without a thorough background check, he invited her to be vice presidential nominee of the Republican Party.
Sensible people of sound mind and character simply don't do things like this. Leaders don't do things like this. Those fundamentally unsuited for the presidency do things like this.
