If Iglesias wasn't enforcing anti-fraud rules and if he tried to block or stall efforts to cull questionable voters from rolls then he should have been fired. Everyone should be concerned about fraud and about people voting who don't have that right. It isn't a partisan issue, or shouldn't be, unless Democrats want illegal immigrants voting.
Hamburger goes on to describe a meeting between Iglesias and a New Mexico lawyer named Patrick Rogers, suggesting that was an attempt by Rogers, who is a Republican, illegally to influence Iglesias. But Iglesias attended voluntarily of his own free will. If Rogers tried to influence Iglesias isn't that any citizen's right? So long as there was no bribe or threat, what's the problem?
