Top 5 ways to make your totally grassroots campaign appear to be astroturfing:

1) be really secretive about your funding sources

2) make your main arguments a combination of debunkable falsehoods and meaningless, yet progressive-sounding euphemisms

3) solicit the help felons if necessary

4) accuse your opponents of paranoia

5) make sure to make actual activists your public “face”

…just sayin’.
