Is there a difference when liberals or conservatives engage in voter fraud?

Well maybe it's just that liberals get prosecuted.

According to prosecutors, Mora and another defendant filled out multiple voter registration forms using fraudulent or duplicate information. Both worked for Acorn, a liberal-leaning group that was the focus of the I-Team investigation into voter registration fraud last fall.

The investigation found Acorn workers were paid based on the number of people they registered to vote, or in many cases, how many completed voter registration forms they submitted to the organization.

Prosecutors believe Mora's sole motivation was money, and was not an attempt to manipulate the outcome of the 2004 election in any way.
