This is a good window into how conservatives have retconned the last forty years to make themselves the heroes, and any excesses or missteps are just written off as "well the crazy liberals forced us to do it."
Attributing the fall from grace of the "small government/libertarians/strong national defense/evangelical alliance" to an antagonistic media (lol) and Obama being a "socialist" rather than acknowledging that decades of conservative "lower taxes/cut regulations" policies - the same stuff ramrouser and others want now - blew up at the end of the Bush II administration and tanked the economy, leading to Obama getting swept in with massive popular support
Accusing Obama of a "hard left turn" in his second term (I would love to hear ramrouser explain what that means and how it manifested itself)
Accusing liberals of forcing conservatives to back Trump because of their crazy left-wing policies while Dems have been running milquetoast centrist presidential candidates (did ramrouser get confused and think Bernie Sanders was the establishment centrist and Hillary was the left-wing populist?)
All of this is probably loosely adapted from various chain emails your dumbest uncle has sent you over the years. Just an effective look at the alternative reality conservatives have crafted to explain why everything is liberals' fault.
The Reagan coalition gave up on Bush in his 2nd term because:
He was pushing hard for a "comprehensive" immigration policy the base hated
He nominated Harriot Myers to the Supreme Court
Katrina
The endless Iraq War and nation building
Obama did turn left ("transform America") in his 2nd term (you will, of course, claim that all of these actions are sensible "centrist" policies).

"I've got a pen and and I've got a phone"

Defers deportations for 4M illegal aliens - far more liberal stance on immigration than in first term setting the stage for Biden's immigration policies

Basically his Administration in the 2nd term was staffed by left wing activists who later formed the core of the Biden Administration.
