From TPM Election Central:
Congressman Tom Lantos (D-CA) might be on the verge of facing a really tough primary challenge. Former state Sen. Jackie Speier claims she has an internal poll that shows her beating Lantos in the primary by a 57%-27% margin. Speier has some name recognition built up after she ran for Lt. Governor in 2006, narrowly losing the Democratic primary, but she has not yet officially announced a campaign against Lantos.
Speier’s pollster also told Roll Call that her poll did not include any push questions, but simply asked, “Who would you most likely support in the Democratic party primary for United States Congress, if the choice was…” and then the two candidates’ names given in rotation.
