I'd like to start a political rumor, see it go viral, and see it change the election. It would be fun in a psychopathically insane kind of way. I like weird rumors. I even fell for the Sarah Palin's child is really her grandchild rumor. The problem is that I just don't have the wild imagination necessary for rumormongering.
Yes, I've written some fiction. Yes, I written grant applications for new projects and had to imagineer budgets for them. But these things have to be rooted is reality. Really good rumormongers are not governed by the rules of time, physics, or common sense.
Take Pam Geller at Atlas Shrugs. She has created a fantastic rumor that Barack Obama is really the lovechild of Malcom X. It's a tour de'force of rumor creation. In her barely lucid screed Pam uses the rumor to tie Obama to both 60's radicals and Black Muslims. She even uses a photo showing the physical similarities between Obama and actor Denzel Washington (who played Malcom X in a movie) to prove paternity.
