I agree that may be a factor in more controversial issues where siding with lobbyists doesn't come at the cost of alienating a huge majority of your constituents. This seems different.

Almost everyone (from what I understand) agrees, so it's a pretty clear case where we should be able to call out those lawmakers and say "you're obviously only doing this for the money/job security - you can't even pretend to be against it on principle."

There are many issues that are in similar spots. The go to strategy to deal with those has been to either:

(1) ignore it completely if it's not getting sufficient media coverage to cause outrage or (2) control the coverage by making it seem as if the public is divided, typically using various forms of poor (but effective) arguments, statistically invalid polling, and research that only gets published if it produces the desired result

I'd say this falls into the first category.
