I haven't weighed in on Obama's choice for Vice President, but DLC founder Al From just made it easy with this quote in support of Evan Bayh:

"The antiwar people cannot define the Democratic Party," said Al From, a founder of the centrist Democratic Leadership Council, of which Mr. Bayh was chairman for four years. "I think Evan's real strength is you get someone on the ticket who has a record of being strong on national security, and that is a very important quality to have."

So Al From believes supporting the invasion of Iraq makes a politician "strong on national security"?

By anyone objective measure, the disastrous invasion of Iraq has done more to weaken our national security than any other action in U.S. history.

• The direct and indirect costs of the war are $3 trillion
• Most of that $3 trillion has gone to the Chinese authoritarians (to buy our every-growing national debt) and the Arab sheiks (for $140/barrel oil)
• The invasion weakened Iran's enemy and enormously strengthened Iran
• While most of the world supported the U.S. after the 9/11 attack, the invasion and occupation turned most of the world against us
• The invasion of Iraq drove up oil and gas prices, which greatly strengthened Russia. Russia is now exerting its new power in Georgia and threatening all of the former Soviet republics
• Bush antagonized our strongest allies in "Old Europe" and thereby weakened NATO
• Bush let Bin Laden escape from Tora Bora and Al Qaeda has grown significantly
• Bush pulled troops out of Afghanistan to invade Iraq and let the Taliban regroup in Pakistan and left Afghanistan in the hands of corrupt opium-exporting warlords

These are the disastrous consequences of the war that Al From, Evan Bayh, and the BushDemocrats supported - and continue to support.

The unprovoked invasion of Iraq was nothing less than a war crime as defined by the U.N. Charter. The war criminals like From and Bayh cannot define the Democratic Party.

Update 1: From the NY Times:

Mr. Bayh’s support of authorizing force in Iraq stands in sharp contrast to Mr. Obama’s oft-stated view that he showed the good judgment to oppose the conflict from the start. After his vote, Mr. Bayh in early 2003 joined Mr. McCain as an honorary co-chairman of the Committee for the Liberation of Iraq, which made regime change in Iraq its central cause.

“He was not only wrong, he was aggressively wrong,” said Tom Andrews, national director of the Win Without War coalition, referring to Mr. Bayh. “In my view, he would contradict if not undermine the Obama message of change, turning a new page on foreign policy and national security.”
