By Taxpayers Association of OregonOregonWatchdog.comThe Vancouver based U.S. Congressional seat #3 in Washington, is one of the few swing seats in the entire country. There are only 18 swing seats out of 435 Congressional seats by some estimates. You now have incumbent Democrat U.S. Rep. Marie Gluesenkamp Perez and Republican State Senator John Braun running as a challenger. With high name ID and strong fundraising, Senator Braun is the most formidable challenger in many many election cycles. Rep. Marie Gluesenkamp Perez almost lost to a primary challenger in her Democrat Primary, showing dissatisfaction among her own party.
