The past year in particular I've been getting as much as daily political fundraising SMS's but every time it's from somebody new. Random representatives from across the country. I reply "STOP" each time and that same one never messages me again, but there are literally thousands and thousands and thousands of people running for state legislatures out there...
I'm fine with Google exempting political e-mails from other commercial spam, AS LONG AS there's a setting to send them straight into the trash.
And I say this as someone who's very politically active -- but there's nothing democratically enabling about getting messages from random reps in Wyoming, Hawaii, Idaho, Virginia, none of which are places I live or can vote in.
