Going to be hard not to certify Trump as President when you will have a Republican House, Republican Senate, and mostly conservative Supreme Court, and Trump won the popular and electoral vote. If Harris doesn't certify him as President, and tries to take power, she'll be immediately impeached and imprisoned. If that doesn't happen, her life would be at risk until she stepped down. Over half the country would be trying to get rid of her. Trump won because of him fighting the weaponization of the justice system used against him. She kept referring to him as being as bad as Hitler after two assassination attempts. You don't do that unless you want your opponent dead. People didn't want the weaponization of government used against citizens who voted for him too. Don't underestimate how truly pissed off people are about what the last administration did to Trump, them, and the entire country. People will take action if she doesn't get out in January. She can leave peacefully, or face a terrible alternative.
