DES MOINES — Gov. Kim Reynolds on Monday signed into law sweeping legislation that will significantly alter Iowa’s elections by reducing the number of days for early voting, restricting absentee voting and threatening county auditors with fines and jail time if they break the new requirements.The legislation was rushed through the lawmaking process by majority Republicans who introduced it and passed it in just over a week with only GOP support.Aspects of the new law, Senate File 413, are similar to those being forged in dozens of Republican-controlled chambers nationwide that seek to clamp down on the voting methods that have mostly benefited Democrats.
