Well, considering that most, if not all, of the allegations originate with the Republican party or points further right; considering that none of these allegations have been verified (although there may certainly be some ACORN employees at fault, many turned in by ACORN itself); and considering that "innocent until proven guilty" is a basic legal concept, I personally see no reason why they should be automatically excluded. Of course, that fact that everyone is entitled to his own opinion is also a basic concept.
