A few interesting linky's that are related to Biden:

First one from a lefty:
Pacific Free Press - Hard Truths for Hard Times
I assumed that Obama was just using Biden to build up some foreign policy cred with the media-thing tank crowd -- the only people stupid enough to believe that Joe Bigen is some kind of foreign policy expert.
Biden poured the filth on them (common people), he joined his campaign paymasters -- the hoggish credit-card conglomerates -- and his ideological soul-mates on the Republican side to drop this bomb (the Bankruptcy Bill) on the hard-pressed working folk he was now claiming to roll up his shirt sleeves and go to work for.
And now it turns out that Biden's son was on the payroll of credit-card behemoth MBNA... for years, as an employee, then as a "consultant," until the bill oozed its way onto Bush's desk to be singed into law. (MBNA is not only one of Biden's biggest campaign supporters; it was also the largest single corporate giver to George W. Bush back in 2000....
Joe Biden voted to give George W. Bush a blank check to wage a war of aggression against Iraq...
Joe Biden eagerly voted for the liberty-stripping Patriot Act; indeed, he claims to be its guiding inspiration.
No one forcede Obama to choose such a running mate. No one forced Obama to make the statement of his own values that such a choice proclaims. It is glaringly, painfully apparent that he has no genuine values, beyond a keen ambition for power. Last week he was denouncing the Bankruptcy Bill. This week he's defending Biden's role in putting together a satisfactory "compromise" on the atrocity, while excusing the flagrant conflict-of-interest in the employment of Biden's son at MBNA.
Whatever happens, whoever wins, there will be more war, more needless death, more mass murder in the name of America. Whoever wins, there will be more state-assisted assaults on working people and the poor. There will be more coddling of the rich, more servicing of the powerful, more injustice, more inequality.

And the choice of Joe Biden as a running mate only confirms this grim fate, which, it is now clear, we must bear out even to the edge of doom -- it not beyond.
