Having set-out the poll-by-poll stats for the four largest Parties (see Overview post) and for the various minor parties (see Santa's Little Helpers post), it's probably well past time to do the same for Left Bloc/Right Bloc support (by far the most important dimension, of course, in an MMP environment).
If I find some spare time, I'll take the stats back to January, but, at the moment, the tables below cover just the last 5 months.
L+G = Labour+Green support
Left = Left Bloc (Lab+Green+IMP) support
Oppo = Left Bloc+NZ First support
Nat = National support
(1)Right = Right Bloc (excluding Conservative Party) support
(2)Right = Right Bloc (including Conservative Party) support
