Trump might have increased his total votes but he's going to finish with the same percentage as '16.

6. Trump already has received over 72 million votes, 10 million more than last time so far

That suggests he did expand his base, it's just that Joe Biden expanded Hillary's voters more (by over 12 million voters). NO doubt that some of Trump's prior voters voted for Joe this time, so it is likely that Trump expanded the number of people who support him. He grew his cult but lost some of his voters as well. We'll have to see how many Trump voters in 2016 voted for Biden when the final polling is done.

The increases were in favor of Joe Biden, but really the two groups of voters canceled each other out. There was a mini-red wave that canceled out the mini-blue wave of 2018, ultimately costing Democrats seats in the House and many of the toss-up Senate races because Trump brought conservative voters out of the woodwork.

Overall, it seems that 46-47% of the people of this country really like trump, no matter what the conventional polls were saying, there are uncooperative Trump voters out there who like him but are not accounted for in polls. Fortunately, 51-52% liked Biden more!
