The easiest way to knock off an incumbent is to face one that is not on the ballot.
"Secret Plan" Sondy Pope-Roberts only got 207 signatures (200 minimum needed). Just thought I would mention that to anyone in the Republican offices in Madison who might be reading this. No particular reason. I'm sure all 207 signatures are perfectly legible and are from residents in the district who will remember signing her papers.
