Keith Olbermann says the representatives' challenge to tomorrow's vote count has found the necessary Senate support:

...it appeared all but certain in early evening Wednesday that House Democrats had secured the support of up to half a dozen Senators to formally challenge the Electoral College slate from Ohio, when the votes are opened before a joint session of Congress tomorrow. Congressional sources tell this reporter that the house half of the written objection — which has the declared support of more than a dozen Representatives — is expected to be signed by Representative Stephanie Tubbs Jones of Ohio. Republican leadership expects the Senate signatory to be Barbara Boxer of California, but this has not yet been formalized. As it is, a written challenge would require the joint session to suspend for several hours, during which the Senate and the House would meet separately and debate the merits of the objection. The ad hoc group formed by Representative John Conyers of Michigan has also today published its staff report, concluding that before, during, and after the election in Ohio, many state laws may have been broken, in every area ranging from the allocation of voting machines, election day "anomalies," and the recount. It recommended a formal Congressional inquiry, and additional legislation to reform voting laws.

If the challenge takes place, it will represent a crucial step in dramatizing the violations of equal protection perpetrated by the current electoral system. And no one will deserve more credit for putting heat on Democratic Senators than Michael Moore.
