Massachusetts Poll: Donald Trump 50%, Marco Rubio 16%, John Kasich 13%, Ted Cruz 10%, and Ben Carson 2%

So the most recent poll for MA by Emerson shows Trump with a ridiculous lead.

I believe this is the first poll I've seen with Trump hitting 50%. What do you think this means for the race going forward?

Weren't the more moderate candidates supposed to have a slight advantage in these states, or am I wrong?

The full data hasn't been released yet, but I also believe this is the first poll to exclude Jeb Bush.
