DES MOINES — With a Marine Corps’ “oorah,” lawmakers on both sides of the issue are girding for a new battle over abortion during their election-year session of the Iowa Legislature.Republican Gov. Kim Reynolds fired the first salvo during her Condition of the State address by telling legislators Tuesday that “it’s time and, unfortunately, it’s necessary” for them to protect the unborn by starting the process of amending Iowa’s constitution to make clear it “does not grant a right to an abortion.”Her call for the new strategy against abortion rights — coming after a judge struck down an attempt she signed into law last year — drew a prolonged standing ovation from Republicans, who hold majorities of 32-18 in the Iowa Senate and 53-47 in the Iowa House.
