I expect the political climate for the next 4-8 years will be at least as polarized as it has been under Obama. On the one hand, liberals will define themselves by their lockstep opposition to all things Republican. That will make them feel virtuous. That will be an article of faith.
Trump is such a wild card that many alternate plot endings are possible. If the economy comes roaring back under his watch, that alone may make him, and the GOP, quite popular. And if America is once again seen to be walking tall in the world, that will bolster his popularity among a major segment of the electorate.
On the other hand, his cronyism and business ties are a scandal waiting to happen. And everyday has the potential for him to set brushfires.
Because George W. Bush was subject to so much relentless, irrational criticism from the Left, that made conservatives spend an inordinate about of time defending Bush. Ironically, if the Left hadn't been so mindlessly, reflexively, and implacably hostile to Bush, conservatives might have been more critical of some Bush policies. But the Left didn't give them the opportunity to put much distance between themselves and the titular leader of the GOP and the conservative movement.
Unfortunately, the same dynamic may repeat itself under Trump. He's such a lightning rod–a role he relishes–that conservatives may feel the need to be defend his policies against knee-jerk opposition and distortion, when, were it not for the Left, they could maintain more critical detachment in relation to Trump. It will be challenging to strike the right balance.
