Item one: "Sen. Ben Nelson told reporters today he will filibuster the health care bill if it doesn't contain an abortion amendment similar to Rep. Bart Stupak's amendment that passed attached to the House health care bill last month."
Item two: "Sen. Susan Collins (R-Maine) has asked top administration officials to make certain changes to the Senate health care bill as part of discussions that suggest her vote is up for grabs"
My crude read is that this is the White House's way of telling Ben Nelson (and Evan Bayh and Joe Lieberman and the rest of them) that they won't get to hold the bill hostage. They've never been particularly committed to the public option, and the Senators from Maine have actually been pretty good on affordability issues. Threatening to go elsewhere for the last two votes is a good way to make temper the demands of the moderates.
Pop quiz: a public option with Stupak rules? Or a crappy trigger without Stupak? Discuss.
