As he and Obama are such good friends I thought he was a sure bet. I wonder if his views on abortion took him out of the running.
...“Sure enough, when Kaine's Republican opponent attacked him for his opposition to the death penalty as Election Day closed in, Kaine invoked his Catholicism in explaining his position. In the process, he ripped a page from the GOP/Christian right playbook: implying he would not tolerate attacks on his faith and tying his position to the pro-life cause, saying, "My faith teaches life is sacred."
After Kaine won, the Democrats tapped him to give the party's response to George W. Bush's first State of the Union address after the Virginia election. The Old Dominion State governor opened with this line: "I worked as a missionary in Honduras when I was a young man, and I learned to measure my life by the difference I can make in someone else's life."
When word spread last summer that Kaine was on Barack Obama's shortlist for running mates, the governor went on the Charlie Rose Show and discussed his support for state-level abortion-rights restrictions, like parental consent laws, a "partial-birth" abortion ban, and requirements for abortion providers to furnish women with information about alternatives to abortion.
All of which suggests the Democratic National Committee's "Faith in Action" team, born under Howard Dean and growing to comprise nearly half a dozen staffers, may be about to get even bigger and more powerful.”
