For months, president Donald Trump and various conservative groups have courted moderate Democrats to join in their plan to overhaul the nation's tax system, which hasn't been significantly changed since 1986.
This week, the Senate will likely vote on a 2018 budget proposal, and Americans for Prosperity, a Koch Brothers-backed group that is pushing for tax reform, is urging Sen. Bill Nelson to vote in favor in a new digital ad released on Wednesday.
"Nelson has hinted at being willing to work with lawmakers on both sides of the aisle to reform the tax code to make it more fair and efficient," AFP Florida director Chris Hudson said in a statement. "This is a once in a generation opportunity that deserves his full endorsement immediately."
Passing the budget plan would enable the GOP to proceed on their tax overhaul without a 60 vote threshold in the Senate, a necessity when Republicans only control 52 seats. Some moderate Democrats like North Dakota Sen. Heidi Heitkamp and West Virginia Sen. Joe Manchin have indicated a willingness to work with Republicans on taxes.
Nelson, one of 10 sitting Democratic senators up for reelection in 2018 in states won by Trump in 2016, voted against a procedural motion to start debate on the 2018 budget on Tuesday. The motion passed on a 50-47 party line vote.
