As far as the Middle East:
First, Obama is absolutely not responsible for what happened in Egypt, it was the people who rose up to get rid of Mubarak. Whether or not his fall will hurt Israel is unknown at this time.
Libya, Bahrain, Syria and all the other countries where the President may have a little more to do with the situation do not affect Eretz Yisrael. In fact, if they’re busy fighting amongst themselves, they won’t be preoccupied with Israel.
Second, it was George W. Bush who promulgated the ‘Road Map’ which used the 1967 borders. Obama has never said or done one thing that weakens Israel more than Bush did. Anyone who thought that Bush was good for Israel must agree that Obama is similarly good. Now, obviously, the question is whether either of them are ‘good’ or ‘bad’ for Israel. I don’t know, and I think that it would take a true expert on Middle Eastern history and policy to judge something like that.
As to the economy:
There is no question that we are in dire straits. This all stems from the collapse of Bear Sterns and Lehmann Brothers in 2007. The question is whether McCain would have done something that may have made the situation better than it currently is. Again, I don’t really know the answer to this, and unless we have a navi in the CR, I am certain that nobody else knows the answer.
Maybe we’d be in a full-fledged depression with McCain, maybe the unemployment rate would be 4%… Nobody really knows. But in response to the original post’s question, I have no regrets with my own choice.
