I see your point but I don't think it's a fair comparison. A lot of the complaints that people had about Obama had to do with policy differences on the margins. For instance he passed health care but didn't fight hard enough for the public option or Medicare for all. Federal enforcement of marijuana laws were eased but he didn't institute a wholesale pardon of people currently in jail or prison for oossession.
Not only has trump done the exact opposite of what he promised, the end result will disproportionately hurt his own supporters.
It would be like a Democrat running as pro choice and then deciding to defund Planned Parenthood as President.
His supporters were Republicans who hated policies promoted by Liberals. But its almost certain they thought those "policies" only benefited minorities.
Like "welfare "queens" even though there are more whites on government assistance than there are blacks in the U.S.
Or that Federal programs went only to those in the inner city, even though poor rural folks simply do not carry their weight and their states regularly rank at the bottom financially.
I'm glad the smoke screen has been removed, because Republicans have hid being religion, racism, and propaganda for far too long.
They really thought a billionaire from NY would be in touch with some rural inbred white folk.
