Why does the NY Primary polling suck so much?

For such a big state with all the attention on it, I haven't seen a single good poll done here other than Siena, and theirs is pretty stale.

The last several polls don't have a party registration screen--this should be a no-brainer in establishing a likely voter model. If someone isn't a registered Democrat, they can't be a likely voter in the primary, as they are guaranteed to not be voting in it.

This isn't the same as asking them whether they ID as a Democrat or Independent, all they need to do is ask what the registration is.

Oy.
