Southwest Washington's 3rd District offers a test of whether the tea party-driven GOP House takeover in 2010 survives. Republican Rep. Jaime Herrera Beutler, first elected that year and twice re-elected with more than 60 percent of the vote, has been out-raised in campaign funding by Democrat Carolyn Long. Herrera Beutler has broken with her party on such issues as health care. But Long has emphasized her credentials as an outsider. The district stretching east along the Oregon border voted for Trump by 7 percentage points.
