Limits on campaign spending is limiting free speech.  People including groups of people should not have their free speech capped, limited, rationed, parsed, edited, or their choices controlled.  People are under no obligation to listen.  There's lot of noise out there.  Shut it off if you don't want to listen.  7 days a week, 24 hours a day,  they have every right to shout it from the roof tops, through the cable, on the internet as often and as frequently as they want.  If they want to take out a super bowl ad and waste millions of dollars they have every right.
