Pelosi is pressuring California Republicans, many of whom are on Democrats’ 2018 target list, to oppose the bill because of the state and local tax issue as well. She brought a cadre of California Democrats to her weekly press conference — normally a solo affair — on Thursday to call out Republicans by name in neighboring districts whose constituents could be negatively impacted.

House Democrats’ campaign arm is also launching a series of digital ads targeting vulnerable California Republicans for supporting the bill. Out of the 14 Republican lawmakers in the delegation, nine are on Democrats’ potential pick up list for 2018.

Schumer and Pelosi are also coordinating closely with progressive groups, who are eagerly painting the bill as a giveaway to corporations and the wealthy at the expense of the middle class.
