Honestly, I don't get how Masters can run 9 points behind Lake. I think it's just too much.
Also, without crosstabs, I don't know how to interpretate the undecided share of vote. If Lake is doing 9 points better than Masters with just 2% of undecided voters in the Governor race, maybe Masters has some room to grow since there are 6% of undecided voters in the Senate race. Just saying, not sure of that.
IA sometimes refuses to post crosstabs, but even when they do, they're usually a hot mess anyway.
