I'm not quite sure I see the point of your question, but I don't think many people think Trump is "cool" in any similar way that they did Obama. People in the rust belt voted for Trump because they hoped he would fulfill his promise to bring them jobs. Most of them still support him, regardless of his stupid twitter rants, even though they are still waiting for those jobs. Obama's popularity ebbed and flowed based largely on his policies. Trump doesn't seem to actually have any, so he hangs in there at the mid to high 30's.
