Actually, I think our fellow Freeper ‘Astronaut’ gave the best reasons up at post #30.
To replace Joe Biden for any other reason than ‘health’ (and even that ‘reason’ would be widely questioned) would demonstrate that Obama is indecisive, sways with the wind, and cannot be counted on.
IOW, a beige George McGovern.
I personally believe it will be Caroline Kennedy. Biden has had several brain surgeries. They will say he has brain cancer ala Teddie and he backs out, only to return later into the Senate. Caroline Kennedy completes the brain cancer circle and launches what the press will call “The New Camelot”.
That hoopla will shout down the switch and indecisiveness stories.
I kind of enjoy seeing all this speculation about Biden dropping out. It just adds more to the notion Biden is washed up and Obama is in trouble!
We'll see. Thanks again.
