The biggest political transformation over the last 10 years has been the decision by the Republican Party to surrender dozens of wealthy suburban House districts across the country to Democrats. The GOP establishment hacks will blame this on Trump’s ascent to prominence in the party, but I attribute it mainly to the disastrous impact of the state and local tax deductions in the 2017 tax reform bill on suburban taxpayers.
That essentially means low tax states are subsidizing high tax states. It was a good move by Trump.
