Hoekstra leads Detroit-area businessman Clark Durant 51-27 percent, a commanding lead.
"Hoekstra’s 24 point lead clearly shows Clark Durant has done too little, too late in this campaign," said Porn. "He should have been advertising and introducing himself to the public much earlier.”
But Stabenow holds a 49-35 percent lead in a hypothetical head-to-head with Hoekstra, a 3-point improvement from the June survey.
The presidential and Senate head-to-head polls carry a margin of error of 4 percent. The GOP Senate primary poll has a 3.5 percentage point margin of error.
