Each system has its inherent drawbacks.

For e-voting --- there is *zero* audit trail. There is literally zero way to determine if an outside influence has electronically altered any particular machine.

For paper ballots --- there is the issue of physically determining a vote. 99.99% of the time the vote is determinable, and the ballots are only needed for recount purposes in something like less than a .5% of the time.

A Florida 2000 situation is probably a once in a lifetime event, if even that.

Florida 2000 and Minnesota Senate in 2008(?) are literally votes that were so extraordinarily close that the 'slop' involved with ballots was greater than the first-announced vote difference.

It is kind of a 'pick your poison' scenario.
