What are the fundamental differences between the 1980 presidential election and 2016 presidential election?

Reagan's win was not controversial. Reagan had experience as a politician, and gave good speeches.

In 1980.......Democrats actually challenged their own sitting president for the nomination.

Ted Kennedy, decided to try and unseat Carter...... and lost.......but the divide split their own party in two.

In 2016........Hillary ran virtually unchallenged, except 2 low probability candidates........ and still lost.

Reagan won the Popular vote. Trump didn't.

There was no Conservative Talk radio, social media, google, Cable News or internet back then.

But both Reagan and Trump rans as Change candidates and as anti-Establishment candidates. In that sense, they were alike.

In 1980, the Republican got more votes.
In 2016, the Democrat got more votes.

The internet and social media

Trump was a Washington outsider who ran as a non politician.
Reagan had been governor of California and Carter was a weak president who dragged America into a bad recession.

Aside from the winning candidate being Republican, everything.
