Sounds like it. However, the Democratic party had some similar notions when I was a child. Most of the deep south were "conservative democrats" aka "yellow dog democrats". That means they hated anyone who wasn't white.
Until about 1969 Australia had the White Australia Policy.
Your Democrats are very similar to our Labor Party both as to the past and the present. One of the things that causes these parties difficulties over the longer term is that one group of supporters are the left wing PC group and on the other side are the blue collar rednecks.
