From the Morning Memo:

With Congress poised to make further gains on its tax overhaul legislation this week, a group is launching a national digital ad campaign to push for the preservation of state and local tax deductions.

The ads from the group Americans Against Double Taxation will target 21 Republican congressional districts, including those in high-tax states impacted by the end of the deduction, including New Jersey, California and New York.

In New York, the group is focusing on three House districts: those seats held by Reps. Tom Reed, Claudia Tenney and John Katko. All three lawmakers voted on the House version of the plan last month.

“Middle-class homeowners in these districts will see their taxes go up due to the cut in the SALT deduction. Poll after poll shows that these taxpayers strongly support the SALT deduction and oppose having their tax dollars finance the large tax cuts for companies and people who don’t need them,” said the group’s co-director, Bob Chlopak.

“Congress has one last chance to stand up for the middle class by voting no on a tax plan that will raise taxes on hardworking families.”

The group says it is a “coalition of state and local government organizations, service providers and other stakeholders” opposed to ending SALT deductions.

The ads warn that ending the deduction of state and local deduction will “raise taxes on the working class” and add to a “trillion dollar hit to the deficit.”

The ads themselves will appear on digital platforms including Facebook and Twitter.

Elected officials in New York from both parties have raised concerns with ending the deduction and Gov. Andrew Cuomo has raised the possibility of a lawsuit to combat it.
