It is not so empty. If you recall, the Thai opposition tried this last summer and almost pulled it off with 356 votes in support, falling just short of the 364 needed. Many senators -- I seem to recall about 75 -- shockingly voted to end their vote for the prime minister position. So some senators have a conscience, though they are under enormous pressure at the moment from the powers-that-be and might not vote the same way again. I believe one-third of the senate has to sign off on it, so 84 needed.
