Good points. But don’t forget that Biden will become president if Obama is impeached and convicted. So if they want to have any chance of winning in 2012, they’ll have to tell Biden not to even consider running. Look for some Democrat to hint that he/she is considering running for president.
Yes, I know. It is sad to say Biden would be an improvement. He may be a clueless dufus, but I don't believe he is a hard-core doctrinaire America-hating socialist like Obama.
