Unfortunately, Giuliani got a lot wrong. A present vote has been called "a soft no". There's also something in Robert's rules about that in order to table a bill (and kill it) you have to have voted positively on it. Ol' Rudy just does not understand or is willing to misdescribe legislative procedure.
Then Rudy said Obama hung out with the Chicago Democratic machine and was slated for the IL legislature. As a matter of fact, Obama has always been an independent Democrat and was never part of the regular Democrats in Chicago or IL.
But I hate to let facts stand in the way of a nice soundbite.
"Obama has defended many of his "present" votes in the Illinois Senate as part of the larger legislative strategy of the Democratic caucus and not a failure of nerve or attempt to conceal his true sentiments from voters.
I'm not here to referee that claim. I'm here to say that there's only one word for the integrity of those who use the raw number of an Illinois legislator's "present" votes to draw a conclusion about him:
Absent."
