And with that $1 donation, you will be on every campaign email donation list for the Republicans from now until the end of time. Word to the wise: If you ever give your email address to a campaign fund (republican, democrat or otherwise), make sure its an email you don't care about or can shut down. No matter how many times you unsubscribe, they just sell your list to the next campaign and use a slightly different name/email/organization to get around spam laws. I made the mistake of donating to a campaign once. Their overzealous and borderline illegal email marketing is what has made me decide to never donate again.
While this $20 for $1 might sound good, especially in the humorous context of taking that $20 gift card and donating it to an opponent, I'm not willing to give my info to a republican campaign and assume they're going to do the right thing and only use it for campaign related activities. Next thing you know, my name will be on the next FCC astroturf campaign about how I hate net neutrality.
