Bluedog Democrats?
What an old reference from 40 years ago.
Like unicorns, blue dog democrats never really existed, except perhaps Fetterman.

The Blue Dog Coalition said of its name:
“The name ‘Blue Dog’ originates from the long-time tradition of referring to a strong Democratic Party supporter as being a ‘Yellow Dog Democrat,’ who would, ‘vote for a yellow dog if it was listed on the ballot as a Democrat.’ Leading up to the 1994 election the founding members of the Blue Dogs felt that they had been ‘choked blue’ by the extremes of both political parties.”
