Senate Majority Leader Harry Reid (D-Nev.) expressed guarded optimism that the Senate could vote tonight on a series of plans to bailout the troubled auto industry – including a potential compromise based on a Sen. Bob Corker (R-Tenn.) proposal. “If they’re able to work that out, the bill will overwhelmingly pass the Senate,” Reid said of the Corker-inspired plan. He described negotiations as continuing in “good faith” and said there is a “possibility, maybe even a probability” that the Senate would vote this evening. “If this thing falls apart, then we would be left with having a cloture vote,” or vote to limit debate, on Friday, Reid said. He said he hoped to have a potential agreement on votes within the hour and expected the Corker compromise language to be completed within minutes of his 5:20 p.m. floor speech.
