The poll was conducted from May 7 - 9, contacting 632 voters.
Ernst: 42%
Mauro: 42%
They've also released some questions that are effectively concern trolling about other Democratic candidates' weaknesses. It's worth noting the primary poll showing Greenfield dominating was fielded prior to the Des Moines endorsement of Franken and before both Franken and Mauro put up new TV ads.

That said, I don't expect Mauro to come close to securing the nomination.

If their numbers are reliable, then this poll is notable in one sense; it's the first in the electoral cycle not showing Republicans ahead of Democrats in this race.
