"Trump's frequent controversies as president have done little to change public opinion about him, with his approval ratings during his first 2 ½ years in office falling into an 11-percentage-point range between 35% and 46%.
By comparison, the average range for other elected presidents since World War II during their first 2 ½ years is 30 points. Dwight Eisenhower had the smallest range before Trump -- 18 points -- but with generally very strong ratings between 57% and 75%"
"Other presidents have had approval ratings during the early part of their presidencies as low as, or lower than, Trump has had. What distinguishes Trump is the lack of very high ratings, such as those typically enjoyed during the first-year honeymoon period of a presidency, or as a result of "rally events" in which citizens show increased support for their leaders."
The part in bold is the downside to the "us versus them" approach so it must be that the GOP thinks it can motivate its base to get out and vote more so then nearly every other voting block combined . . in the five states that matter.
This is why people call for reform of the electoral college. A deeply unpopular/controversial 41% President can win because all he needs is to win 3-5 states.
