So what does the DNC's announcement that Joe Biden and Evan Bayh will be speaking on Wednesday night of the Convention -- the night the VP candidate speaks -- do to their VP odds?

Who knows? But there's no end to the tea-leave reading.

From the Wall Street Journal:

The public announcement--maybe--means they are not going to be Barack Obama's running mate. The still-unnamed vice presidential candidate is scheduled to headline Wednesday evening at the convention in Denver.

Vice-presidential tea-leaf readers have been examining the slow roll out of convention speakers trying to divine clues on who the vice presidential candidate may be. On Sunday, the DNCC announced Hillary Clinton would speak Tuesday night. On Wednesday, the DNCC announced Gov. Kathleen Sebelius of Kansas--another rumored prospective veep--would speak Tuesday night as well.

And ABC News:

But before the veepstakes rumor mill, desperate for even the slightest hints, rules out Bayh and Biden as running mate possibilities, sources close to the process note that anyone penciled into a speaking slot could be shifted into the vice presidential candidate's slot later that evening.
