One of the key races for the US Senate this fall will be in Iowa, where Republican Chuck Grassley will try to win his seventh term. Tuesday, during the Iowa primary, Democrats will choose their challenger.
The four Democrats include former Lieutenant Governor Patty Judge and former state senator Tom Fiegen, plus current state representative Bob Krause and current state senator Rob Hogg.
In northeast Iowa, Democrats in the 1st Congressional District will choose a challenger for incumbent republican Rod Blum - either current Cedar Rapids mayor Monica Vernon or former state representative Pat Murphy. Murphy lost the race to Blum two years ago.
Some crowded races will be decided Tuesday in Scott County during the Iowa primary election, by both Democrats and Republicans.
Three Republicans and two Democrats are hoping to succeed retiring Sheriff Dennis Conard, while seven Republicans and six Democrats are competing for two seats on the board of supervisors.
Two from each party will advance to the November ballot, to replace retiring supervisors Jim Hancock and Tom Sunderbruch.
Polls will be open in Scott County, and across Iowa on Tuesday, from 7 a.m. until 9 p.m.
