After announcing he felt that Obamacare was a "train wreck" he apparently decided to run . . . away.
The senator's retirement comes as a bit of a surprise, as he'd just raised a hefty $1.5 million and has nearly $5 million on hand. Baucus was the last remaining Democratic senator who faced serious questions about whether he'd run for reelection.
But Baucus faced a challenging political landscape.
He helped guide President Obama's healthcare law through Congress, but last week said he feared a "train wreck" as the law was implemented.
"I just see a huge train wreck coming down," Baucus told Health and Human Services Secretary Kathleen Sebelius on Wednesday in comments that were mocked by Republicans. "You and I have discussed this many times and I don't see any results yet."
Baucus has had key roles in the last 12 years in moving through Congress the healthcare reform legislation, several major tax bills including the Bush tax cuts of 2001 and trade deals with Central American nations and several other countries.
