Speculation that Senator Joe Biden of Delaware will be Senator Barack Obama's choice for vice presidential running mate is heating up.
For several reasons, Biden is a sensible choice. He fills several of the bottom line needs Obama has from his number two. Maybe.
First, Biden is a mature, experienced office holder. He can play Lyndon Johnson to Obama's JFK.
Second, Biden may be seen by many general election voters, by virtue of his long service on and chairmanship of the Senate Foreign Relations Committee, the reassuring national security presence that potential Obama voters concerned by the Illinois senator's seeming lack of an overall foreign policy, national security vision.
But Biden does not fit the bill for the third critical quality Obama needs in a running mate. He isn't from the South.
I still think that former Georgia Senator and one-time Senate Armed Services Committee chair Sam Nunn is Obama's best choice for a running mate, the one who can help him the most, especially in the Peach State, which may prove critical this November.
A major downside to Biden is that his version of the Straight Talk Express, while usually refreshing, can sometimes get him into trouble, as happened earlier this year when his characterization of Obama as "articulate" was seen as condescending and racist.
