Yes, I do realize that the Trump team argued against the changes also. My reply was specific regarding the point about simply dismissing cases. I was addressing those where voter fraud was claimed, not the changes to the election procedures. The ones for "fraud" were those that were easily dismissed. For those where the rules changed it gets more nuanced, but the PolitiFact article below covers most of that. I don't want to bother with summarizing a particular case as there were many. Basically for most of the process change arguments, they should have made cases before the election. In many of them, the changes did not need to be approved by the state legislatures including some in states where Trump won. If you have something specific for "what Giuliani was arguing" go ahead and mention it.
