What it basically means is that in GoP heavy areas, they slowly siphon votes from the GoP candidate to the Dem candidate just enough to reduce the candidate's "lead" in an area.

Here's a very rough idea of how it affects things. (Intentionally oversimplified as requested.)

Let's say a state has a 2 counties.

One Country county gets 150 votes for Trump and 25 for Biden.

The City county gets 275 for Biden and 250 for Trump.

Now, the results in this case would be 400 for Trump and 300 for Biden. Trump only wins 1 county but the whole state. You with me so far?

Now let's say you wanted the machine to "cheat" but not make it obvious. You know Trump won't win the City and Biden won't win the Country. So what do you do?

You tell the machine, late at night when nobody's watching, to take 50 of those "Country" votes and put them in Biden's bucket. Trump still "beats" Biden in the countryside, but now the totals are like this: 350 Biden 350 Trump.

It's basically embezzling votes. You take a little bit where they "won't notice", over and over again, in county after county after county, until Trump's lead from the rest of the state is pretty much nullified, and the "city" votes (legit or not) are the only ones being "counted".

But what if the President's lead is so huge you can't get away with it?

Well, just sit around Detroit manufacturing votes, of course!
