Check out these archived articles at HillBuzz, I remember reading a good one about 2 months ago about Kirk.
May explain why he voted this way!

Both Democrats and Republicans have something like this where closeted gay men of public prominence can meet guys for sex and fun without blowing their covers. Republican Congressman Aaron Schock, for example, used the Chicago Young Republicans organization extensively through the summer of 2009 to meet hot young guys here in Chicago. We know of several guys who dated Schock through the CYRs and these guys were chosen because they are ambitious, bisexual/questioning, and closeted themselves so they could be trusted to keep Schocks secret. We imagine people like Mark Kirk, Lindsey Graham, Larry Craig, Eric Massa, Mark Foley, Charlie Crist, and others had similar arrangements with Cocktail Party Republican establishment organizations that introduced these closeted gay men with young, attractive guys who could be trusted not to talk about doing whatever they were doing with politicians. These are NOT male prostitutes but rather young men who want to get ahead in the GOP, so theyre willing to give a little head fill in the blank if you know what we mean. Not every guy is as attractive as Schock, but if you knew anything about the CYRs youd see just how many guys in a groupd like that would love to do just about anything to have a Congressman write him letters of recommendation especially in this economy.
That article is typical of most homosexual literature ~ but that doesn't mean Kirk isn't gay.
