I dunno how much it cost exactly but I'm sure that making and distributing "Hillary: The Movie" cost a lot more than 50 bucks. Limiting individuals to that total is a restriction on their speech.
Now, maybe that's a restriction that we want to impose but it's disingenuous to say it's not a restriction.
I'm less concerned about campaign finance reform in general as communications tools get better; producing a great viral video is something a person with "no money" can do and contribute to a campaign, whereas running $10mm of TV ads requires...$10mm.
