Republican U.S. Sen. Chuck Grassley leads Democrat Mike Franken by 8 percentage points among likely Iowa voters, according to a new Des Moines Register/Mediacom Iowa Poll — a first look at what could be Grassley’s most competitive election since 1980.
Grassley leads 47% to 39% against Franken, a retired U.S. Navy admiral, in the latest poll, conducted July 10-13 by Selzer & Co. Another 7% of likely voters say they would vote for someone else, 2% say they would not vote and 5% say they are not sure.
While Grassley leads Franken, the margin is narrower than in any Iowa Poll matchup involving Grassley since he was first elected to the U.S. Senate. Grassley has not polled below 50% in a head-to-head contest since October 1980, before he went on to defeat incumbent Democratic U.S. Sen. John Culver.
