Next limit voter registration to exclude people unlikely to vote for your candidate! Then limit early voting after a storm so people can’t get to the polls! And then, try to trick or intimidate people at the polls, telling them they’re not allowed to vote!
Then register dead people to vote and encourage them to vote again and again and again, using disguises such as fake mustaches and hats and such, and make sure to ferry them around town to different polling places!
And if, after all that, your side still loses, then sue and get your father’s buddies on the Supreme Court to overturn the result! But if you win, say the other side has to accept the sham result, you know, for the good of the country.
