It was just the 2010 mid terms in November (on my birthday, yey!). That's when we vote for our congressman, senators, representatives, as well as other local offices and state laws. Come January the winners of those elections take there place in their respective office, and if it means a large regime change the period of time in between can some times be crazy with the pushing and pulling of last minute power. This is referred to as a "lame duck session", where sometimes politicians leaving office will vote wildly do to any lack of repercussions (they already lost, and won't be running again, what do they have to fear).
This term's change over has come with debates about 'homosexuals in the military', 'citizenship for illegal immigrants who serve in the military', 'medical assistance for 9/11 responders (firemen and the sort)', 'extending tax cuts', and other stuff. The last of which is the big one on the Republican docket, to which they refuse to vote on anything else until the 'tax cuts' are voted on... by which they mean they won't do anything until they are extended (and a huge boiling pot of controversy sits in that one).
Many believe this is crap of them because the other hot topics on the docket are pretty important as well... but alas are also very controversial too. Homosexuals and illegals, how... un-American.
McCain sits at the center of this with the 'gays in military'. He has repeatedly asked for more and more studies and information from the military about how it may effect morale. Every time they say "it'll be fine and the majority feel it won't effect them at all", McCain demands more studies and waiting about to be done on it. It seems a huge chunk of both the nation and military are ready to do what the rest of the western world have done with their militaries, but McCain is stuck in his old ways. I find it strange really, especially with his military background, and his wife who happens to be on the other side of the fence on the matter. Whichever though, it's the story of one politician swinging his gusto around to sway the government from the mass opinion to his own...
Now the heaping pile of American controversy just laying there is just asking for a trolling... hence our weariness to your question.
