this is true, but not what is bothering people.
this is bad reasoning and not terribly relevant.
Let's look at the progress he has supposedly made.
This has not happened. There is Trump lawsuit asking a court to block a county from extending the time to cure ballots, but the county has not agreed to do so, and the judge has not granted the motion. Currently, the ~93 ballots at issue are segregated from other votes cast in that county.
Now, because this occurred in a county that voted Biden, Trump could cut Biden's lead in one state by as much as 0.18% with this lawsuit. That's not a strategic move. It doesn't move the dial in a meaningful way.
It's also not clear why this is a good thing at all: it would have the effect of eliminating legally cast votes with technical errors (such as illegible signatures or including incorrect forms of ID). This is not to be applauded, and undercuts Trump's defense of only challenging illegal votes.
They are doing an automatic recount. The recount is automatic per Georgia law because the race was narrow. This was not caused by anything except that law. There is no Trump strategy here.
There is an audio recording of him walking back his claims. (When specifically asked if he stands by his sworn statements, he said "at this point? No."
The following day he said he was tricked into recanting, and then that he didn't recant at all.
He recanted, even if he is now recanting that recant.
Additionally, this was precipitated by a third party, not by Trump, although his original affidavit is now being used in a Trump lawsuit.
Assuming this is in reference to the "glitch" in Michigan county, this was not discovered due to a Trump lawsuit. It was discovered by a county election official before the Trump campaign took any actions. Again, no Trump strategy.
This is nonsense. The swing states that stopped counting had warned well in advance of the election that they wouldn't finish the count the first night due to the high volume of mail-ins and lack of resources to count all of them. I'm not sure where you got "pretend" from, either.
It's also not part of a Trump strategy.
Only one of the things you pointed to was caused by Trump. It has not succeeded. And it does not involve enough votes to change results at any level.
Moreover, this is a strawman. The issue isn't an "investigation" - things like the local elections being fixed happens organically as part of the certification process, such as in the VA-5 in 2018.
The issue is preemptively declaring victory and repeatedly asserting that your political opponents engaged in widespread criminal activity to falsify the election results, and doing so before an investigation. You are assigning Trump a much more reasonable position than he has actually taken, giving him credit for things he is not responsible for, and then taking umbrage at the fact that people are criticizing him - even though they are criticizing him for something much more substantial than you've assigned to him.
