"Yellow dog Democrats are Democrats who are fiercely loyal to their party, typically voting a straight Democratic ticket and always supporting Democratic candidates. The Democratic party of course greatly appreciates yellow dogs, although the term is sometimes used disparagingly to describe people who are blindly loyal to the party. Some Democrats have suggested that a small amount of disloyalty might actually be a good thing, allowing people to come up with constructive suggestions for making the party stronger.
The use of the term dates back to around 1900, when it was used to describe Southern Democrats, and it became popularized during the 1928 Presidential contest. Many Democrats in the South had lingering resentments against the Republicans left over from the period of Reconstruction after the Civil War, and as a result they decided to stand behind the Democratic party, sometimes at all costs, rather than supporting Republicans. The yellow dog Democrats were a serious force to be reckoned with in the American south as a result."
I'm a yellow dog democrat and guess I'll always be one. I truly don't like to discuss politics with others, especially those who make derogatory and inflammatory comments about the candidates I support.  Please keep your rhetoric to yourself and I won't throw shade on the candidate of your choice and goodness knows there is more than enough shade to throw! You vote your way and I'll vote my way.
