After the brouhaha over the White House's maybe-maybe not effort to float Snowe's trigger as the compromise (started with Mike Lux, confirmed loosely by Greg Sargent and by Brian Beutler, but later denied by Sam Stein and walked back by Lux himself--let's just say that situation is fluid), the issue is moot as far as the Speaker of the House is concerned:
Pelosi (D-Calif.) rejected the idea of a “trigger” for a public option. That means that the government-run healthcare plan would be a fallback option, enacted only if other reforms didn’t make healthcare more accessible....
“I don't even want to talk about a trigger,” Pelosi said at her weekly press conference. She said the “attitude” of her fellow Democrats is that “a trigger is an excuse for not doing anything.”
Something else for the slowest moving legislative body in the history of critical legislation, otherwise known as Max Baucus's Finance Commitee, to keep in mind.
