The Trumpsters won’t care. They think we’ve never had higher GDP, that NK is no longer a threat, that the debt doesn’t matter anymore, that coal is roaring back, and on and on and on.
In other words, they reject reality and insert their own in their adulation of Trump.
Most people tend to judge the world from the perspective of how they are doing, not the overall trends. Ronald Reagan won the Presidency in 1980 while repeatedly asking Americans “Are you better off today than you were four years ago?” Given the oil crisis fo the late seventies, the answer carried Reagan to the Presidency. Every presidential election is a referendum on the previous four years.
May be a matter of personal taste, but I dislike the style so many conservatives have fo announcing "Liberals all think _____ " and they then provide a position that is too stupid for any self-respecting person to endorse. Why don’t we just let Trump supporters speak for themselves. Putting words in other people’s mouths tends to discourage dialogue.
However, one only has to look at this forum and elsewhere to see that Trumpsters truly don’t care. As the OP pointed out, it’s nothing but broken promises and flat out lies. Yet he enjoys 90% approval with the GOP.
I feel confident in saying they absolutely will not care.
As Nate Silver has pointed out, Trump’s high approval within the GOP is based on two trends:
The # of declared Republicans is shrinking
There’s been a 15-20% swap-out as Romney/McCain style Republicans switch to being Independents and Independents who dislike the Romney McCain wing of the Republican Party switch to the party of Trump.
The less diversity in the party, the greater the degree of uniformity in opinions, but this is the sort of trend that leads to the Republican wipeout in 2018.
