In 2013, Rep. Steve Scalise from Louisiana introduced an anti-carbon-tax resolution that earned 155 co-sponsors. While the measure did not get a vote, in 2016 the resolution passed 237-163, but with only 82 cosponsors. Because resolutions are non-binding and only last the duration of a Congressional session (two years), in 2018, Scalise went for it again. The 2018 version passed 229-180, but the number of co-sponsors was down to 48. Cue 2019 and the resolution (unlikely to see a vote in the Democratic-controlled chamber) is down to 22 co-sponsors.
