'best' president to the MAGA\gop is meaningless.
nothing is easier to convince than a cohort where feelings matter more than facts, and identity supersedes reality.

let's take trump's most popular issues :

currently , it seems to be immigration.
what he promised : to deport illegal immigrants that are violent criminals.
what we got : mass deportation of anyone of suspicious color\accent at unlimited expense, including citizens with no due process, many with no criminal history.
(hint : the latter was what the gop actually wanted, with taxpayer funded commercials and propaganda reminders of their 'success')

last year, trump's most popular issue among the gop was affordability.
there is almost nothing one can say on this topic except overwhelming denial of their daily experience.
the accelerated concentration of consumption at the top is certainly not by the bulk of gop voters.

this list waxes\wanes in sporadic popularity of gop issues like fiscal conservatism, pedophilia; all quantitative disasters to be manipulated but mostly discarded from media coverage.
