The other thing we have to ask ourselves is; if the Gubb are losing money from NG; why are they not howling for it's removal, or why haven't they removed it after it was reintroduced back in the '80's??
They did try it back in the 80's, and it didn't seem to improve things (affordability), so it was reintroduced soon after.
Considering that the percent of the total voting population enjoying it is not that large, it's not exactly going to be a vote loser...if anything; it would be a vote winner - given the current level of public and lefty-media noise about it's perceived evils.
