It's largely flown under the radar, but the Waxman-Markey climate bill could come to a vote today. And there are only 184 confirmed 'yea' votes. Not quite the 218 needed to pass.
Benen passes along this AP description of the effects of the bill:
"It fundamentally will change how we use, produce and consume energy, ending the country's love affair with big gas-guzzling cars and its insatiable appetite for cheap electricity. This bill will put smaller, more efficient cars on the road, swap smokestacks for windmills and solar panels, and transform the appliances you can buy for your home."
