This is what "certain" people have done before:

Democratic districts have their voting machines shipped to other districts leaving a shortage of machines and long lines that extend for more than 6 hours while the polls close and turn large crowds away.


What can be done?
Volunteer to be a poll administrator.(most are old feeble and easily manipulated)
Vote as EARLY AS POSSIBLE
investigate machine availability and correct problems by October.
Get court injunctions to prevent police from turning away lawful citizens who simply want to legally vote.

any other ideas?
