Is there a DO NOT CALL registry for the campaign? I've already voted blue. I'm a registered Democrat.

Currently living and voted in Ohio but previously in Minnesota.

I'm getting 1-2 phone calls or texts a day about Biden, from various unions orgs, or whatever. Every time I've politely tell them I've voted, take me off the list. For 2 weeks now. It's becoming almost harassment. 

If I was an undecided voter I can totally see this as a major turn off. 0 contact from the other side.

Is there a way to deal with this?
