It happened slowly at first, then suddenly political satire was everywhere. I don't know when exactly the turning point was. It might have been 8 years of Bushisms that provided the kindle for the fire. Or maybe the absurdity of the 2008 election cycle was the turning point, when an SNL skit discredited a Vice Presidential candidate in the eyes of an entire generation.
Lost in the short-term attention commanded by Donald Trump in the first Republican primary debate was a long-term problem for the party, created by questions that compelled the candidates to take positions at odds with a majority of Americans. While the debate questions were smart and sharp, they were also predicated on many conservative litmus tests. When the subjects of abortion, same-sex marriage, immigration and religion were aired, they elicited responses that, while pleasing to a core constituency, will be a tough sell in the general election. Adherents can get their news in a manner that validates their beliefs, notwithstanding that the objective of those outlets is to draw clicks from adherents based on controversy that would not exist in a world of compromise.
