After an ugly primary campaign involving accusations sex trafficking, fake polls and threats of lawsuits, Arizona’s 1st Congressional District Republican appear to have selected a nominee to take on Democratic incumbent Tom O’Halleran.

State Sen. Steve Smith called on rival candidate Wendy Rogers to drop out of the Republican primary for Arizona’s 1st Congressional District and threatened to sue her over radio ads and a website.

Republican Wendy Rogers is entitled to run for Congress despite flaws in her nominating petitions, the Arizona Supreme Court ruled Thursday.
