I stated: In each case, the Democrats submit that somehow, any means of identifying a voter will impact mostly on minorities.

I showed that this methodology was widespread, and linked to a simple search that turned up several examples just on the first page.

From the very first link:

In a letter sent today to officials at the U.S. Department of Justice (DOJ), the Florida Equal Voting Rights Project called on the DOJ to object to sections of the Florida electoral reform package that will have a discriminatory impact on minority voters if implemented.

"Rather than moving forward into the future, the provisions in question threaten to return minority voters to the Jim Crow past," said Howard Simon, Executive Director of the ACLU of Florida, which operates the voting rights project in conjunction with the Florida Justice Institute and Florida Legal Services.

...The Project's letter objects specifically to three aspects of the omnibus Florida electoral reform act as adversely affecting minority voters: (1) the posting of the Voter Responsibilities list that harkens back to literacy tests; (2) the new felony purge process; and (3) the disqualification process for provisional ballots.

Other links claim that requiring ID would be specifically hard on minorities.

That specific enough for you? What the hell do I have to do here? I feel like when I'm trying to point something out to my dog and he keeps looking at my finger.

I maintain that the behavior of the Democratic Party when any form of regulation on voting fraud is proposed, seems to indicate a strong reliance on less-than-kosher votes for victory.
