U.S. Reps. John Shadegg and Jeff Flake, stalwart conservative Republicans from separate areas of the Valley, filed Monday for re-election.
Unless GOP opposition materializes before the filing deadline of 5 p.m. Wednesday, the two will be unopposed in the Sept. 10 primary. Dusko Jovicic, who announced he would run against Shadegg, is now aiming for the seat being vacated by the GOP's Bob Stump.
Shadegg, 52, is seeking his fifth term to represent the newly drawn Congressional District 3. The north-central Valley territory between Glendale and Scottsdale runs from Anthem on the north to as far south as Thomas Road.
Flake, 39, is completing his first term and has pledged to serve no more than three terms. He is seeking to represent the new District 6, which covers most of the southeast Valley.
Shadegg said he is well recovered from heart-bypass surgery in March and is adhering to a rigorous exercise schedule.
The backgrounds of the two representatives converge at the Phoenix-based Goldwater Institute, a conservative think tank. Shadegg, an attorney, was a founding director in 1988, and Flake became its executive director.
Shadegg is chairman of the Republican Study Committee of more than 70 self-defined House conservatives. He said his main accomplishments involve holding down government expenditures and taxation and striving for long-term reform of health care.
Democrat Charles Hill, former budget director for Phoenix, is also in the District 3 race.
Flake has been a leading advocate of restoring normal trade with Cuba.
The National Taxpayers Union rated him second-highest in the House, behind Rep. Ron Paul, R-Texas, for acting in taxpayers' interest.
Chandler Democrat Deborah Thomas and Oro Valley Libertarian Joe Duarte also are campaigning in District 6.
