Sure. But fixing some issues that have always been around doesn't change the fact that Biden won big. The polls all showed it, people didn't believe them, he won. He as up by 7% in the lastest polls, he won by about 3.5%. He was barely up in AZ, won by 12K votes, etc..

It was just a fundraising ploy from Trump and Co. Nothing more. 

Since this was a big Trump victory, nobody is hardly even talking about the slow ballots in Arizona, the Milwuakee late ballots, etc..  detroit having the issues they had, and so on. The reason: These things have always happened. I have been in the news business for 2 decads covering elections. They always happen, and they did this year. However, since it isn't close and he race is called, nobody cares.  

The GOP was much better in lawsuits this year for polling delays and lines, hours, etc.. That helps. 

As I stated before, Trump can thank Charlie Kirk for AZ, PA, WI, and a bit in Michigan. their ground game this year was incredible with the young voters.

Without it, he loses. Doesn't mean the Dems cheated of course.
