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.
