He may crack 400 electoral votes.
I don't think so. The DNC, RNC, and media will be gunning for him from every angle, no matter who his opponent will be. He pulled off a miracle win in 2016, winning several key big states by razor-thin margins. That will not be allowed to happen again.
Trump took 46 Electoral Votes in 3 states with less than a 1% margin of victory. (MI 20 EV and 0.23%, PA 16 EV and 0.72%, WI 10 EV and 0.77%) He lost one state, NH (4 EV, -0.37%) with a margin under 1%.
If you don't think that the RNC, DNC, media, Russians, Chinese, illegal aliens, and creepy porn lawyers can't manufacture 0.7% in just 3 states... well then, we are in disagreement.
The difference in MI, PA, and WI could have been reversed with a total of just 77,750 votes... out of 130 million nation-wide votes... 0.06% of the total... and the Dems are importing illegals by the thousands each month, for 48 months.
Those 46 EVs make it a Dem win, 258 to 273 (no matter where the 7 "faithless Electors" go)
(Add in FL, 29 EV, and 1.2% margin... just 112,000 votes... to make it a massive Democrat victory, 309-229.)
Below is the May 17 2016 prediction map, just for reference...
Also interesting to note that the polling data attached to that map showed a Gravis Poll, taken May 10, 2016, that had it exactly correct Clinton 48, Trump 46... Actual result was 48.18% to 46.09%...
and, of course, CNN/ORC 28 April to 1 May was off by 11 points total Clinton 54, Trump 41.
No, he won’t be any where near that number. His base has not grown in the last 2 years or so. 2020 will be a very tough race for a number of reasons.
I see him winning about what he got the last time. He might pick up New Hampshire and Minnesota and he might lose one of the other Midwest states he won the last time. Essentially a wash as it were, but I don’t see any R or D winning 400 electoral votes anytime soon.
