Gallup really fails, I think, in this, that has gotten a little bit of coverage.

Sure, they label it as “opinion”, but it’s coming from the CEO:

Explaining Trump: Widespread Government Corruption

[…]

Guns — a symbol of freedom from government tyranny to many people — are now a key voting issue. A quarter of U.S. voters say the presidential candidate they vote for must share their view on guns.

[…]

That is just ahistorical. Guns have been a rallying cry since the early 70’s for self-labeled conservatives.

The CEO of Gallup put together a laundry list that frankly makes me suspicious that he’s a closeted Trump supporter.
