Palin's lack of experience is an INSULT to the office of the vice presidency. Her clear lack of understanding of the prescient national security issues (or really, any major issue) of the day should disqualify the McCain/Palin ticket to anyone who hopes for a safe and stable country.
The Powell endorsement is huge and it's a shame that FOX and the Republican media is going to stoop to attacking Powell's character because they have nothing else. The man is a national hero, former secretary of state, former general and has an 80% approval rating nationally before this announcement. After the Republican slime machine gets done with him though, who knows.
I hope intelligent people come to their senses and listen to Powell because what he said on MTP is absolutely right on target.
