NY,PA,WI-CBS/YouGov: Sanders/Cruz in WI; Clinton/Trump in NY, Trump in PA

[Mehmentum]

Winning by 2 points in Wisconsin would be underwhelming for Sanders, as would winning by 10 in New York be for Clinton.  Neither result would really change the delegate math situation, however.

SO WAIT...............

Hillary leads Sanders by 18% when only factoring in registered democrats, EXCEPT NY is a closed primary so there shouldn't be any independents in this poll, right?

Independents can register as Democrats for the purpose of a primary and still identify as independents when asked.

At the same time, they would have had to be registered as a Dem in December to vote in New York.  I hope they accounted for this, but we will see.

Huh. I thought the registration deadline was sometime in late March.

The deadline to change registration between parties was in December.  The deadline to register as a new voter was in late March (yes, its stupid).
