"GIVE HIM A CHANCE"

I have lived through the Administrations of 15 Presidents and only once before did I hear the Presidents supporters plead "Give him a chance".  He, like the present President-elect was inexperienced in addition to having won with fewer popular votes than his rival.  His administration was a complete disaster and easily the worst, in my lifetime,  But the question remains, why are Trump's supporters pleading for us to "give him a chance"?  Trump surely has the Electoral College votes; both Houses of Congress are in Republican hands and shortly a majority of Justices on the Supreme Court will have been appointed by Republicans.  Why then are Trump supporters pleading "give him  chance"?  Do they feel the same foreboding as the rest of us and asking us to back up their political opinion to help them cope with their own dread?
