State Assemblyman David Valadao’s campaign for the new 21st district released a poll last Tuesday that showed the Republican ahead of his Democratic opponent by 20 points.

On Friday, the campaign of John Hernandez, CEO of the Central California Hispanic Chamber of Commerce, released its own poll that showed the Democrat much closer, with Valadao ahead 41 percent to 37 percent.

The Valadao poll, conducted Oct. 8-9 by Moore Information, surveyed 400 likely voters and had a 5-point margin of error. The Hernandez poll, conducted Oct. 13-15 by FM3, surveyed 400 likely voters and had a 4.9-point margin of error.

Until recently, the race had attracted little interest from outside groups. The GOP-aligned Crossroads GPS announced a significant buy last week in this

majority-minority district to assist Valadao. Neither national party’s House campaign arm has gone on the air here, though the Democratic Congressional Campaign Committee launched robocalls last week.
