The only people still supporting Trump are those who have appropriated the term 'Conservative'  to justify their greed and cruelty.  Today Conservatives are nothing more than hacks who are paid to keep the money flowing uphill while they clutter up the minds of gullible voters with empty promises of fixing the system. 
Actual Conservatives who have an instinct for a business-centered, small town set of beliefs and support principles invoking smaller government are appalled by Trump.
