For some, ignorance is bliss, but for Democrat Jon Tester, it’s an important campaign tactic.

Sure, the second-term senator from Montana isn’t up for re-election until 2018, but that won’t stop him from using disingenuous attacks on the wealthy to scare his constituents into sending him campaign cash.

“Today, it looks like the billionaire Koch brothers are trying to crown themselves the new Copper Kings,” wrote Tester — or some lackey — in a weekend email to supporters. The Copper Kings of the 1800′s were the industrialists who colluded to buy power and influence in the U.S. Senate.
