Conservative group: Rubio, 18 House Republicans were perfect

Only a handful of Democrats, meanwhile, voted with the group 20 percent of the time. One Democratic senator, and 21 House members got a zero score. 

The AFP scorecard use 35 Senate votes, and 22 House votes from the last Congress, and only scores lawmakers on votes dealing with the economy. The group takes a special interest in energy issues, including sponsoring a pledge in which lawmakers vow to oppose any climate change bill that raises revenues.
