2020 is a long ways away

It almost feels like the 2016 election still lingers, yet 2020 candidates keep throwing in their hats. The economy seems meh. Unemployment is low, but job growth has stalled. Not sure what exactly the "Blue Wave" is trying to accomplish, but they have a lot in common with the Tea Party from 2010.
People raised tons of cash under the guise of Tea Party mantras, so have the groups under the "Resist." mantra.
Mitt Romney wasn't much of a Tea Party type, yet won the nomination only to lose handily in the general election.
Would be nice if Trump proposed a balanced budget that could placate the less absurd GND elements.
Why not simply tax abortions or at least make them as expensive as delivering a live baby? Tax prostitution. Tax recreational drug use. Tax pornography.
By taxing non-essential surgeries and risky life choices, one would hope the choices would be less frequent.
