Republicans will not field a candidate for two of the top slots on the Oregon ballot, further complicating the party's efforts to break into statewide offices they haven't held for nearly two decades.  The candidate filing deadline came and went Tuesday without any Republicans signing up to run for an open seat for Attorney General or to challenge Treasurer Ted Wheeler, a Democrat. Oregon Republican Party Chairman Allen Alley says he couldn't find high-caliber candidates who could compete with well-funded Democrats.
