The Arizona AFL-CIO has unveiled its endorsements in this year's U.S. House primaries, though only one of the candidates is actually engaged in a primary, and one primary was bypassed altogether.

All candidates who received endorsements were Democrats, and included the four Democratic members of the Arizona House delegation, though none faces a primary. Other recipients were Bob Lord, who is taking on U.S. Rep. John Shadegg (R-Phoenix) in the 3rd Congressional District; John Thrasher, a Democrat who is running for the second time against U.S. Rep. Trent Franks (R-Glendale) in the 2nd Congressional District; and Ann Kirkpatrick, the front-runner in the 1st Congressional District Democratic pack.

"These candidates share our vision of what is important to Arizona’s working families," said Rebekah Friend, the Arizona AFL-CIO's executive director. "It is crucial for the future of Arizona that we elect those who are going to step up to the plate and fight for the issues that will move Arizona forward. We’re convinced that these candidates will do just that."

Friend vowed that the AFL-CIO would "put substantial resources forward to educate union members and their families on the views of our endorsed candidates and then ensure their successful election.”

Of the seven candidates, only one, Kirkpatrick, faces a primary challenge. Fellow Democrats Jeffrey Brown, Howard Shanker and Mary Kim Titla are also running to take the Democratic spot on the ballot, but Kirkpatrick has received the lion's share of endorsements and contributions.

One race was completely ignored by the AFL-CIO: the 6th Congressional District, currently represented by U.S. Rep. Jeff Flake (R-Mesa). Two Democrats, Chris Gramazio and Rebecca Schneider, are vying for the chance to take Flake on, yet the race received no attention from the labor group.
