I'm not sure which group you are thinking about but it may have been similar.
I always enjoy the Capitol Steps holiday specials, but they do recycle some of the material from previous shows so it isn't all new. Good political humor can be hard and of course what's funny depends a bit on your political persuasion. I think most of the members of this group used to be congressional staff workers, mostly for conservative officials, but they take aim at both sides of the aisle.
They spoofed health care reform with Mr. Obama in a vigil (Think Linus from the Peanuts Halloween special) waiting for a single-payer health plan to rise up from nowhere:
"I have the most sincere single payer pumpkin patch in the entire world"
They also spoofed the Obama-was-born-in-Kenya theory with a song about "Secret Kenyan Man" (to the tune of "Secret Agent Man") and Fox News with "Glory, Glory Paranoia" to the tune of "The Battle Hymn of the Republic"
There were some one-liners:
"I was working less than a tooth fairy in West Virginia"
"Job leads were getting colder than Ann Coulter stamping passports at the Mexican border."
