You are right, he most likely will not be impeached, only because some Republicans do not want to endure the wrath of King Trump and risk losing their seats.
I may be wrong too, but I think this process will help defeat Trump. His die hard fans will, of course, vote for him. I know of a lot of people who only voted for Trump because they hated Hillary, that he was the lesser of two evils. After 4 years of Trump I can't see any of those folks voting for him again. I also think there were a number of people who just didn't vote because they assumed there was no way Trump would win.
Bottom line, even though I doubt he will get impeached, I think these hearings are providing verification that Trump will go to any length to benefit himself, not the American people.
