Dodd and Biden drop out of race for Democratic presidential nomination
After getting trounced in the Iowa caucuses yesterday, Democratic Sens. Chris Dodd (Conn.) and Joe Biden (Del.) dropped out of the presidential race. Dodd was the only candidate who supported a corporate carbon tax as a means to fight climate change; both Dodd and Biden supported a cap-and-trade system to reduce greenhouse-gas emissions 80 percent below 1990 levels by 2050.
