The court of public opinion is more important than even the regular courts.

Trump team needs hammer on simple made-for-media talking points and slogans every American can grasp

for example

PA 138K Biden votes, no Trump Votes. Who believes it?
GA 500K mail in ballots - almost zero rejections
WI more votes than registered voters in places
MI tens of thousands of ballots arriving in the middle of the night - all for Biden
This is Banana Republic stuff!

The court of public opinion is more important than even the regular courts.

Both play an essential role.

Of course, if Trump had the effective support of Republican members of Congress there would be little doubt of the outcome. The points you set out above would do just fine.
