Now, if you ask these people why they think the president should be impeached, you will probably hear them repeat some hash of Benghazi and Fast & Furious and Solyndra and ObamaCare and IRS and tyranny. Maybe you’ll hear something about the NSA, but that’s more likely from independents and Democrats. Overall, most of these folks will mention something that is either entirely made up or is completely overblown. It will be something they heard on hate radio or watched on hate television. This is what makes them think the president deserves to be impeached, but they’d want pretty much any Democrat removed from office because they don’t like Democrats.
Then there’s the rare honest voter who will say they think he should be impeached because he’s black.
The Bold emphasis is mine.
