RANDOM BIDEN-RELATED OBSERVATIONS…. While the political world digests the big announcement about Joe Biden joining Barack Obama on the Democratic ticket, I thought I’d pass along a few random observations.

First, Obama/Biden is only the second Democratic ticket in the last 35 years not to have at least one candidate from the South.

Second, if Obama/Biden wins in November, Biden will be the first Roman Catholic vice president in American history.

And third, Biden happens to be up for re-election in Delaware this year. As I understand it, he will, like Joe Lieberman in 2000, run simultaneously for both seats.

Just thought I’d pass these along.
