Rep. Mark Kirk’s (Ill.) desire to avoid a Republican Senate primary in 2010 has apparently been dashed. The Associated Press reported Saturday that a retired state judge plans to seek the GOP nomination.Former Judge Don Lowery, 62, who spent 26 years in the First Judicial Circuit in southern Illinois told the AP that he is worried about the economy and deficit spending in the federal government.Kirk, who has signaled his plans to run for Senate but has not formally announced his bid, has worked in recent weeks to clear the GOP field.Democrats are continuing to sort out their field for the competitive open-seat race. The seat is held by appointed Sen. Roland Burris (D), who has already said he will not seek a full term next year. The seat previously had been held by President Barack Obama, who resigned from the Senate after winning the White House election last fall.
