To start...separate post marks past mid-night, Look for irregularities...ambiguous markings...lots of computer searches? Lots of Trump Lawyers.
Problem with your plan is that Trump doesn’t have enough lawyers. You can bet the RINGOS in the RNC won’t spend a dime on them unlike 2000. Trump needs to challenge four states and several jurisdictions in GOP states. I doubt his campaign has the funds required to do a proper job and with Deutsche Bank about to drop the hammer on him, I doubt he can provide the needed cash.
