From Lisa Jackson, head of the EPA:
Since the beginning of this year, Republicans in the House have averaged roughly a vote every day the chamber has been in session to undermine the Environmental Protection Agency and our nation's environmental laws.
These are, of course, all symbolic votes, since none of these bills are going anywhere in the Senate. Still, symbolism is a pretty good way of getting a read on what a party's real priorities are. And you never know: if they win control of the Senate next year, Republicans might turn out to actually be serious about this stuff. Best not to take chances, I think.
