Oh yeah you're totally right when it comes to this. This is why I said that if Democrats are doing it then why aren't Republicans doing it -- the reason is that it isn't happening (at least on the scale that some are talking about).
Lol on the Space Force thing, but yeah -- the Feds are the people that investigate this, so if Trump really thinks that he can back his claims he could form task forces and such to combat this. Could literally just sign an executive order tomorrow directing them to investigate claims of this.

He already did that, and the localities refused to cooperate by providing the required information.

It really comes down to the fact that there are more Democrats that don't vote than Republicans, and if we make it easier to vote, there will be more Democrat than Republican voters who wouldn't have voted otherwise.
In other words, anything that makes it easier to vote = win for Democrats. Harder to vote = win for Republicans.
When Democrats try to make it easier to vote, Republicans accuse them of allowing voter fraud.
When Republicans try to make it harder to vote, Democrats accuse them of voter suppression.
That's how it's been for years. It's just politics.
I'm sure if it were the other way around, we'd see the same arguments being made. Democrats would be the one pushing laws to make it harder to vote and Republicans would be accusing them of voter suppression.
Trump is taking it to a whole new level. In 2016 he said lost the popular vote by 3 million votes only because there were up to 5 million illegal votes cast for Clinton. He's already laying the ground work for 2020 claiming it will be the most rigged election in history. He's also convinced many that there is exactly a 0% chance that he will lose in November. A narrow Democratic victory in Nov could actually be a disaster.
Democrats don't vote because their party is shit and their voter base is unmotivated. Who can blame them when they repeatedly disenfranchise the population like they did with Bernie over and over trying to force feed their establishment candidates. It is not difficult to vote. What you call "making it easier" is really just making FRAUD easier, which is what Democrats depend on to maintain control.
Regarding Clinton's "win of the popular vote"...
