U.S.: Sen. Byron Dorgan, along with his 60th vote, plans to retire
- The North Dakota senator was seen as super-vulnerable. The clock is ticking on the Democratic supermajority in the Senate, which promises to have many kinks in its armor come November. With Dorgan’s retirement, the seat will likely flip to the Republican column. Even before this, he was seen as one of the most vulnerable senators. Peace, brah. Loved the three terms. source
