Looks like The Ventura County Republican Central Committee is basically admitting they were responsible for the push poll attacking Republican Linda Parks. The committee is controlled by many people that are loyal to Tony and Audra Strickland. Some of them are current employees/consultants for them.
Here is Timm Herdt's article.
When the push poll was first reported this was the response from Strickland's office:
Rondi Guthrie, a spokeswoman for Strickland, said the assemblywoman was not aware of the survey and does not know who might have commissioned it. She said Strickland is focused exclusively on her job in the Assembly.
If it is true, as it appears, that the VCRCC was involved with the poll it is wild to think her close political allies, employees, and supporters didn't tell her they were conducting a push poll to support her. But I guess it could have been a surprise present or something.
