nycpix is right. This quote refers specifically to wars in Iraq, by the way. "This time around" as opposed to 1991-- with the mildly cynical (and cyclical) implication that there might be a third one.
The guy (Larry Elder) was talking about a senator who also voted against the war in 1991.
So, did he want to say that the senator is kind of stubborn by persisting on doing something contrary to what is, according to Larry Elder's mindset, the right thing to do? I mean, did he try to say that the senator will always have that position no matter what?
There's an album by Hanson called "This time around"? What do you get when you read only that on a CD cover? It's like "We did it again" ?
Although now I understand the idea, there seems to be certain connotation according to what you both said that I still can't decipher.
