Note, please, that we seem to be back to one source for this information — “an extremely credible source,” but Reid did not use a plural.  Earlier in the week, Reid claimed to have “a number of sources,” and that “the word is out.”  So which is it?  One extremely credible source from Bain who somehow got to look at Romney’spersonal taxes for a ten-year period even though no one would have access to that except the Romneys, their accountant, and the IRS?  Or a number of sources who say “the word is out”?  Reid’s sounding more and more like Joe McCarthy every day
