Amanda Renteria is a Democrat challenging Rep. David Valadao in California’s 21st district. She also has a perfectly good campaign website, [site link removed].
CA-21 is currently Lean Republican according to Cook, but if this is the level of competence that Rep. Valadao will be facing then that categorization may change soon. And not to Ms. Renteria’s benefit.
[UPDATE: Apparently, I have to spell this out: Ms. Renteria’s ‘official’ site is a NRCC-based one that’s attacking her.]
