A new poll shows 44 percent of voters still don’t know who they want to nominate in the Democratic Senate primary race. The results also show Rodney Glassman retaining his lead, while he and Randy Parraz have received more traction than they had in previous polls.

Parraz commissioned the poll from Winning Connections, which surveyed 417 likely voters Monday night in an automated telephone poll. The margin of error is 5 percent.

Though there’s some shifting in the field in this poll, Glassman retains his lead within the margin of error, at 20 percent of the vote. Parraz moves up to 17 percent, John Dougherty has 11 percent and Cathy Eden drops to fourth place with 8 percent of the vote.

Compare those results to a Rasmussen poll from late July, which showed Glassman with 15 percent, Eden with 11 percent, Parraz with 10 percent and Dougherty at 7 percent.

The high number of undecided voters less than two weeks from the Aug. 24 primary historically means many of those people won’t vote, said Michael Trujillo, Parraz campaign manager.

Parraz holds a big lead among Latino voters, at a 7:1 margin over Glassman, a Parraz news release said. Trujillo said the Parraz campaign is predicting high Latino voter turnout, which would keep the race between Glassman and Parraz close.

Other campaigns have used Winning Connections for polling, including the National Education Association, the Democratic Congressional Campaign Committee and in Arizona, U.S. Rep. Gabrielle Giffords and the Arizona Values Coalition.
