The proposal, which Democratic drafters say will reduce the deficit by $1.85 trillion between spending cuts and tax increases, passed narrowly 50-49 on a largely partisan vote at 4:56 a.m.
A handful of Democrats, all up for reelection next year and representing conservative states, voted against the measure: Sens. Kay Hagan (D-N.C.), Mark Pryor (D-Ark.), Max Baucus (D-Mont.) and Mark Begich (D-Alaska). Sen. Frank Lautenberg (D-N.J.) was absent.
