Why are several Republican congressmen repeatedly bucking President Donald Trump?

This question has gone unanswered for nearly a year. Seven Republican congressman have repeatedly stood in the way of the president’s priorities, while also bucking House leadership. Reps. Brian Fitzpatrick (R-PA), Mike Lawler (R-NY), Nick LaLota (R-NY), Rob Bresnahan (R-PA), Don Bacon (R-NE), Max Miller (R-OH), and Riley Moore (R-WV) have a lot to answer for.
