State Rep. Mark Lofgren, a Republican, announced Tuesday that he will challenge four-term Rep. Dave Loebsack, D-Iowa, in the 2nd District, according to local reports.
Lofgren marks Loebsack's first challenger, but news reports say that Republican Mariannette Miller-Meeks is eyeing a run as well.
Last cycle, Loebsack defeated Republican John Archer by a 13-point margin in the district. President Barack Obama won the district with 56 percent.
Rothenberg Political Report/Roll Call rates this a safe Democratic seat.
