How to stop the 51st state talk - IMO

So, the states have to agree to all the fine print, which kicks off a big election with no secret ballot - because who needs secrets, right? If the vote is in favor of joining the states, we become the 51st state. But, if the vote is in favor of staying with Canada, those who voted to join the states will be like, 'Oh no, I'm a US citizen now!' and get deported to the US border, where they'll be greeted with a MAGA hat , handgun, and a 'Lets go Brandon' t-shirt.
