Republican Joni Ernst leads Democratic Rep. Bruce Braley by just one point, according to a Des Moines Register/Bloomberg Politics poll released Saturday.
Among likely voters, 47 percent favored Ernst and 46 percent favored Braley.
This latest poll shows the Iowa Senate race tightening. A late September Des Moines Register poll found that 44 percent of likely voters supported Ernst and just 38 percent supported Braley.
According to TPM’s Polltracker average, Ernst leads Braley by 4.3 points.
The Des Moines Register surveyed 1,000 likely voters Oct. 3-8 with a margin of error plus or minus 3.1 percentage points.
