Nevada Rep. Dina Titus, a first-term Democrat, drew her first official Republican challenger Tuesday when banker John Guedry filed paperwork to open a campaign committee.

Guedry, who has been testing the waters for the 3rd District House race since spring, released a statement saying his campaign launch marks the beginning of “the journey to rebuild a level of trust between our government and the people.”

Guedry also claimed Nevadans “are fed up with the reckless spending and lack of accountability in Washington.”

Guedry told CQ Politics in June, as he was planning for his bid, that he recognized that “anytime you take on an incumbent it’s an uphill battle.” But he said he was eager to contrast his private sector experience with the long political tenure of incumbent Titus, who was a state senator for 20 years (the last 16 of those as the chamber’s Democratic leader) and ran a competitive but unsuccessful campaign as the 2006 Democratic nominee for governor.
