Comment: An old school Alaskan Democrat is somebody that votes in every election yet hasn't seen one of his or her candidates win for 2 generations. In other words, with the exception of Mark Begich in 2008 and Barack Obama in 08 & 12, no Democrat I've voted for has won a statewide or national election since the early 80s...maybe even the late 70s.

My preferred candidates must have racked up 60 or so losses in Alaska elections since the 80s. That's why I can't stomach the Sanders dead-enders. I didn't whine, quit and throw in the towel when my candidates lost election after election after election after election. But geez, their guy loses one election and they're wearing MAGA hats. This Moberly guy's grapes are so sour he's ready to back any right-wing extremist Alaska has to offer.

The Sanders dead enders got what they wanted...Hillary isn't president. So I don't know what they're still whining about.

Ex Output:
Non-identity-attack
