When you've been around as long as I have, you hear that about almost every president. At least since Reagan. The opposite party says the same or something very close. Republicans were calling those who followed Obama as Obama cultist or Obamabots.
So if one has a differing political view, a very partisan political view, is highly loyal to a political party while think the other evil, be it the president or political party or both. That's not uncommon.
It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
