From the release:
In a statewide Emerson College poll released today, Texas Senator Ted Cruz is not only leading Trump 36% to 35% in the upcoming primary, but Cruz is only trailing Hillary Clinton by one point in a hypothetical general election matchup, 46% to 45%.
In contrast, Trump is trailing both Clinton and her Democratic rival, Bernie Sanders, by the same 9-point margin of 47% to 38% in a potential general election match-up.
There is absolutely no way Cruz is down to Clinton by only 1 point in Wisconsin. The primary results may be accurate or nearly so, but Cruz will not come within 10 points of any Democrat in Wisconsin during the general.
