Voters in 12 states re-elected 93 percent of 530 state lawmakers who supported a gas tax increase between 2015 and 2018 and ran for re-election in 2018. Winning state lawmakers in Nov. 6 races included 92 percent of Republicans, and 94 percent of Democrats, according to a new analysis from ARTBA’s Transportation Investment Advocacy Center™ (ARTBA-TIAC).

The results are consistent with those from the last five years that show support for a gas tax increase does not hurt political careers. Including 2018, voters have re-elected 92 percent of nearly 1,900 state lawmakers who voted in favor of a gas tax increase since 2013. This support for lawmakers who approve a gas tax increase persists across party lines as well— over 90 percent of Democrats and 94 percent of Republicans were re-elected.
