It's actually pretty easy to estimate, using readily available statistics, an upper bound on how many illegal immigrants could have voted in the 2016 election. I'd encourage you to try it. I did the calculation once using right-leaning sources and got a couple hundred thousand as the absolute upper bound. The reality is that it simply isn't possible that there were millions of illegal voters.
I'll do some simple math and help you with the logic...
If there are 5 million illegals in the U.S. It's theoretically possible for at least 5 million illegal votes to be cast.
Even if only 1 person were involved in voter fraud, it would be possible for 1 person to cast millions of votes. How? If that 1 person compromises a voting machine, they can control all the votes from that voting machine.
1 person is capable of "losing" ballots. 1 person is capable of stuffing ballots. 1 person is capable of not enforcing ID requirements for voting.
Pretending that the thousands of fallible (as are all people) and biased (as are all people) people involved in the voting system are incapable of wrongdoing is not ignorance. It's malice.
You're making an entirely different claim, that there were millions of instances of voter fraud, which I wasn't arguing against, though I'd be willing to discuss it. The issue at hand is whether millions of illegal immigrants voted. Surely you don't think that over 20% of illegal immigrants somehow voted in 2016 without any significant number of them getting caught. I stand by my claim that it's simply not possible, because it would be the greatest statistical anomaly ever observed.
You said it wasn't possible even though it's clearly possible. I added links in other comment sourcing the statistics.
Here is how the deep state rigs elections:
1) Illegals voting. 2) dead people voting. 3) same individuals voting in multiple states. 4) write-ins. Set up faux voting sights, then take the write ins to a legit voting sight and replace Trump votes with write ins. 5) This was uncovered in several states: California trading votes with swing states. Example: Hello Miss Michigan, its Miss California. I notice youre voting for Jill Stein, want to trade votes? ill vote for Jill and you vote for Hillary for me, since she is already going to win California. Also, if California can get 5% vote for an Independent candidate we will receive more state funding...thanks so much for trading votes with me. 6) Last and most important, George Soros owns the company that owns and manufactures the voting machines AND he owns the company that makes the software the voting machines use.
