Regarding a vote for Joe, I don't think so, not for me. It's because of his religion that I won't vote for him. There I said it, totally politically incorrect! However, there are real reasons for this decision.
The Arab world already believes the U.S. is taking orders from Israel, a Jewish President would (in my opinion) push the Islamic moderates over the edge. It would be the same as pi$$ing on someone else's shoe.
The second reason is a real concern about What Joe would do and When. He is Orthodox. The first debate the democrats had was on a Saturday. He said he would attend until after sundown, he really did. That makes scheduling very difficult. Lieberman would go on TV until after the sun when down and Kerry turns into a Werewolf at 10PM.

Only a short window of opportunity.
But really, we need a president 7/24. If Joe is not willing to work on the Sabbath, that's his right, but this is a real cause for concern. If there is a rocket coming from Korea late Friday night, I'd like Prez with his finger firmly on the button.
Once I've heard Joe renounce his Orthodox views, I'll give him a second look. I do have a doctor who is Orthodox, he agrees that being the President would be very difficult for someone of that ilk. Israel has never elected someone of that sect.
Stay healthy,
Andy
