The Iowa Senate race is tied.
A new Suffolk University/ USA Today poll released Wednesday showed Republican Joni Ernst and Democrat Bruce Braley in a 40-40 deadlock.
Their battle to succeed veteran Sen. Tom Harkin, a Democrat retiring after 30 years, is one of the most closely watched in the nation.
“If you drive north into Iowa on I-35 coming from Missouri, you’ll see a landscape full of red counties far to the left and blue counties far to the right,” David Paleologos, director of the Suffolk University Political Research Center in Boston, said in a statement.
Never miss a local story.
“The poll pits Democrat Braley’s congressional district in the northeast against Ernst’s Senate district in the southwest, but the voters in between will make the difference,” he said.
Independents could make the difference. Braley leads 80-5 among Democrats. Ernst is up 77-5 among Republicans. Independents prefer Ernst, 39-36 percent.
