WASHINGTON (AP) — Unanimous but far from united, the Senate advanced legislation to prevent a partial government shutdown on Wednesday, the 100-0 vote certain to mark merely a brief pause in a fierce partisan struggle over the future of President Barack Obama’s signature health care law.

The vote came shortly after Texas Sen. Ted Cruz held the Senate in session overnight — and the Twitterverse in his thrall — with a near-22-hour speech that charmed the tea party wing of the GOP, irritated the leadership and was meant to propel fellow Republican lawmakers into an all-out struggle to extinguish the law.
