Since we are in an election cycle ...
The origin of Yallow Dog democrat always crack me up:
https://en.wikipedia.org/wiki/Yellow_dog_Democrat
In the 1900 Kentucky gubernatorial contest involving
Kentucky Governor William Goebel, Theodore Hallam
was criticized at a Democratic Party meeting for
first supporting Goebel, then campaigning against him.
The critic pointed out that Hallam earlier had said
"if the Democrats of Kentucky, in convention assembled,
nominated a yaller dog for governor you would vote for
him" and asked "why do you now repudiate the nominee
of that convention, the Honorable William Goebel?" Hallam
responded:
"I admit," he stated blandly, "that I said then what
I now repeat, namely, that when the Democratic Party
of Kentucky, in convention assembled, sees fit in
its wisdom to nominate a yaller dog for the governorship
of this great state, I will support him — but lower than
that ye shall not drag me!
