Politico has this item about FreedomWorks PAC backing David Castillo, a financial adviser running for the open 3rd District seat.
Castillo has ties to the group, having worked for a predecessor, Citizens for a Sound Economy. Also declared on the GOP side of the campaign is state Rep. Jamie Hererra from Ridgefield.
Politico reports that the endorsement is important because Hererra was attracting most of the mainstream Republican Party support.
The seat is open because incumbent U.S. Rep. Brian Baird has decided not to run again.
