Did I Miss Something

I concede that I only half paid attention to the news for the last 4 days, I was in San Angelo, TX visiting my friend and his family, but in all the brouhaha over the cap and trade bill that passed the House, I notice it hasn't passed the senate yet. So, what's the point? Time and again I've seen where the conservative Dems in the senate vote out the most progressive parts of these bills and end up with weak half-measures designed to stop Rush Limbaugh from saying mean things about them.

How is this one any different?
