As Rush Limbaugh revealed last week, the “grassroots” #StopRush movement was founded by a small number of hardcore political activists and is maintained by a core group of about 10 people who account for 70 percent of all #StopRush tweets to advertisers. Real live actor and comedian Tom Arnold gave the campaign a boost Monday by joining the #StopRush crew.

Followers were quick to pile on, although some forgot to add their hashtags.

So, Rush needs to be stopped because he won’t open his house to fans? Is that it?
