Here's my idea for a 2 part series finale.
Election day is coming and Pres Martinez is getting all nerveous because he finds out he is losing in the populatiry polls. Cory does whatever it takes to try and get the message out to get Pres Martinez reelected. Episode ends by finding out Pres Martinez loses the election fairly.
Election day passes and Pres Martinez prepares for life after president. Cory and his dad find out that they can't live in the whitehouse anymore because the new pres chose their own cheif. The episode ends at the airport with Pres Martinez, Cory,Victor and anyone else involved all saying goodbye as Pres Martinez moves back to where he was from(don't know where he was from)and Cory and his dad go back to San Fransisco.
After the elections passes yesterday this is sorta how I came up with that idea. I don't really watch this show but based on what I have seen, this would be a great,shocking ending
