He wouldn't have to worry about re-election. He could take out the mobs with the insurrection act. He can pardon political prisoners. He can finally get control of the debt and deficit spending. He can set an agenda to prevent anchor babies. If the House flips and Senate remains, he could enact legislation that prevents Senate and House abuse of power... he can get this shit done cuz he doesn't have to worry about re-election.
If he wins, it will be hard for a couple months with all the REEEE-ing and violence, but it will end, and we will bounce back.
It will be wonderful.
