The careers of most politicians would crumble under the heavy scrutiny that the self-proclaimed toughest sheriff in America now faces.

But despite a mountain of legal troubles, Maricopa County Sheriff Joe Arpaio remains popular with voters and has more than $3.4 million in the bank for his November re-election campaign.

The Justice Department sued the five-term sheriff on Thursday on allegations that his officers racially profile Latinos – a move that has his critics saying that voters will finally be turned off and his supporters saying the development will only make him more beloved among voters who want a tough sheriff who doesn’t back down from anyone.
