I suppose it’s a little difficult to make predictions about a possible eight-year Trump presidency but what can be seen right now is an ever-growing irrelevance of the Democratic Party combined with Trump fulfilling a lot of the promises he made on the campaign trail. It’s safe to say he’ll maintain his base going in.
There were a lot of states this election that started off “likely Democrat” and then gradually shifted to “battleground” during the campaign and these Trump didn’t lose by much.
Colorado–shifted to battleground from leaning Clinton
Virginia–arguably likely Clinton-leaning Clinton and arguably battleground
Pennsylvania–went from likely Clinton-battleground
Michigan–was likely Clinton and went battleground
On this list, Trump won Pennsylvania, Michigan, and Wisconsin which were unexpected.
The main thing to note about those states is industry. People there rely on industrialisation.
Going into 2020, Trump may already be able to lay claim to the following states–
Possibly also a strong stake on Maine CD2. BUT…states he lost by about 5-6% margins in are as follows:
Which could mean that 42 electoral college votes from those states are understake. If Trump hangs on to all of his and snags these states, he would end up with a 342-196 victory over his next challenger.
But all of this is pure conjecture at this point.
