Former President Donald Trump’s new tax proposals targeting specific subsets of voters are a policy reversal from the long-sought Republican goal of broadening the tax base while lowering overall rates.

In fact, should Trump be successful in imposing some of these tax ideas, for instance, a deduction for interest on auto loans and exempting taxes on Social Security income, it would represent a return to some of the tax policies that last existed in the early 1980s, before the Reagan Revolution.
