Sen. Chuck Grassley is narrowly ahead of Democrat Mike Franken, according to the latest Des Moines Register Iowa Poll. The Republican, seeking his 8th term, led Franken by three points, 46% to 43%. The survey, of 620 likely Iowa voters, has a margin of error of 3.9%. It was conducted by Selzer & Company, rated A+ by FiveThirtyEight.
We don't often highlight individual polls, particularly those that seem to be outliers. Grassley led by double-digits in two other recent polls, and most forecasters don't have this race on the competitive radar.
However, what caught our eye was that the same survey found Republican Gov. Kim Reynolds with a 17% lead over her Democratic challenger, Deidre DeJear. That result was pretty much right in line with other polls of the gubernatorial race.
