First, the nation was divided. Donald Trump did not create that division. And it will continue. I am more interested in defining why the division exists and why, to all appearances, it will continue.
When you say ‘handler’ I take it to mean personages who represent the interests of specific ideological and economic faction in the nation, with different plans and ideas about what policies and directions are “good for the nation”.
The advent of neoliberalism, in my view, is the essential culprit, which had earlier beginnings, but was accelerated under Reagan and the neoliberalism infected the news.
1. Under neoliberal 'laissez-faire' thinking, Reagan repealed the Fairness Doctrine ( where a news station, if they aired a view for 5 minutes, they would have to give equal time to an opposing view, for political speeches. ) This enabled Rush Limbaugh, Hannity, and 'hate-the-left' radio on AM.
2. Prior to Cable, there were only three broadcast networks, and it was generally understood that the news programs were not profit centers, and were there under the auspices of 'civic duty'. News programs in prior to cable tended to be non--political, and where there political discussion, it was relegated to sunday mornings with Buckley's firing line, etc. With the advent of cable, 25/7 news, CNN being the first, the only way they could survive with that kind of coverage, since that is all the network was about, news, etc, having to earn a profit means they have to cater to news that was popular, so the various news show coalesced around left and right points of view, each carving out their niche. IN this scenario, the 'echo chambers' were created, further widening the divide.
(Under neoliberalism, even news has to earn a profit ) so news for profit is the source of the problem, plus the fact of the repeal of the Fairness Doctrine, led to right wing hate-the-left radio, Rush Limbaugh, Hannity, and this led to the toxic hurt the left by any means justified politics of Newt Gingrich (when he became Speaker under Clinton), which later gave rise to the T Party, then the Freedom Caucus, the divide ever widening and this resulted in a clever opportunist sensing a vacuum in a particular demographic that was beckoning for a demagogue, enter Trump, and in Trump they found their champion, and the great divide we find ourselves today
The essence of the thing is neoliberalism took America, and over the news.
The enemy, in my view, therefore, is
neoliberalism.
