Seconded

John Cole's response to the "Firebaggers"--the ideologically liberal purists who've complained incessantly about the President's inability to achieve the agenda he campaigned (while ignoring or underplaying Congress' role in such "failures")--is delightful. Cole aims his criticism at a specific few commentators at Balloon Juice, but it's applicable to the larger group of ideological purists:

"My problem is you morons can’t tell the difference between holding someone’s feet to the fire and burning someone at the stake."

I concur.
