So I apparently never bothered to update my party affiliation. I used the opportunity to troll them.
Today I received in the mail my 2019-2020 DNC party survey.
For my number 1 domestic issue I checked "other" and wrote in "Build the wall."
For my number 1 international issue I checked "other" and wrote "Make mexico pay for the wall."
Under the comment section where they ask how to make the democratic party better I wrote "Start helping Make America Great Again."
Under the donation section, I checked "other amount" and wrote "$0.00", checked the box "I have enclosed a check for the amount with my survey." and actually enclosed a check, made payable to the DNC for the amount of Zero dollars and Zero Cents.
