There is a robust movement in America by some to deprive others of the right to vote.

Voter fraud is the cover story for this movement. But I don't think that is the motive.

A case bouncing around in federal court in Philadelphia shows just how tenacious the movement can be.

See if you recognize these people:

They don't care about facts.  They make grandiose claims about widespread voter fraud while driving efforts that disenfranchise legitimate voters.

They don't care about evidence. They keep making those claims despite having no proof.

They don't care whether a federal judge tells them they have the law all wrong and suggests that sanctions might be in order. They just keep filing legal briefs.

The group behind the case, the American Civil Rights Union, saw its initial effort to knock Pennsylvania felons off the voter rolls rejected on Sept. 9 by U.S. District Judge C. Darnell Jones 2nd. Now they are appealing to the U.S. Third Circuit Court.

Nonpartisan voter rights groups Project Vote and Demos called that an "unnecessary purge" in legal filings last week.

Voter fraud fabulists won't let facts or reality get in the way of the bogus story they want to tell you.

That has to make you wonder, right?  If history and facts show that these efforts keep legitimate votes from being cast, could that be the real motive?

In the ACRU case, the group has repeatedly claimed that the Philadelphia City Commissioners are violating the National Voter Registration Act by not removing the names of incarcerated felons from the voter rolls.

That was the "incorrect recitation" of law that prompted Jones to wave the possibility of sanctions at the ACRU, which then claimed its argument was "incomplete" but not "dishonest." Jones apparently didn't buy that, either.

At the center of the case is an issue settled in state court 16 years ago.  In Pennsylvania, people convicted of felonies lose the right to vote while incarcerated. They regain that right as soon as they are released. The feds defer to the states on this issue.

Linda Kerns, the local attorney for the Virginia-based ACRU, said she thinks that "most Pennsylvanians would be shocked to learn that ineligible, incarcerated felons remain on the voter rolls in the commonwealth. If the court will not remedy this issue, then the legislature must take action."

Let that sink in. The ACRU misrepresented the law so badly a judge considered sanctions.

And while appealing that judge's ruling on the law, the ACRU relies only on the guess that you will find this shocking and a request for politicians to change the law.

Felons from Philadelphia are incarcerated all over the state, which had 48,951 inmates as of Jan. 31 -- 47.7 percent were black, 41.4 percent were white, 10.2 percent were Hispanic, and 0.7 percent were some other race.

Still in search for the motive, I asked Kerns whether the ACRU just wants to require all those inmates to re-register to vote upon release for the legal right they get back automatically as soon as they are free.

The Pennsylvania Department of Corrections released 18,397 inmates from prison last year -- 51.4 percent white, 38 percent black, 10.1 percent Hispanic, and 0.5 percent were some other race.

Kerns decided that was a question she didn't want to answer.
