Ted Cruz has opened up a 10 point lead on Donald Trump in Wisconsin, per the latest survey from the respected polling unit at Marquette University Law School. This result is directionally consistent with recent polls showing a shift in the race, but it is the first survey to find the Texas Senator with the outright lead, beyond the margin of error.
Interestingly, Trump's support is unchanged, at 30%, since the last Marquette survey in late February. Both Cruz and John Kasich saw significant gains, picking up voters that previously supported a now-withdrawn candidate or who have made up their mind in the final few weeks before the April 5 primary.
On the Republican side, Wisconsin has 42 delegates, 18 are winner take all for the statewide winner, while the other 24 are winner take all based on the vote within each of the state's 8 congressional districts (3 per district).
For the Democrats, Bernie Sanders leads Hillary Clinton by 4 points. The last Marquette survey showed Sanders leading by one point.
