How does President Trump still have supporters?

So I just saw his announcement about running again. I was also one of those people that thought that that wouldn’t happen since he lost the last election so bad. Now I’m starting to think he actually has a chance again. <br><br>I am 17 so I don’t really have much political knowledge but I read he is running on the “most conservative agenda” yet he hasn’t said that till now. Does anyone really believe him? I know politics is a big game and much more complicated that what I know but I’m seriously confused how he could still get support after all this stuff that he has done and said.
