It doesn't matter who you support as a democrat, the DNC reserved the right to run rigged primaries... they said so when Bernie supporters sued them over the 2016 election...
I won’t be endorsing any candidate in the primaries. I’ve grown too mature for that. I’ll wait for the general election; At which time I will jump whole-hog behind ANY Republican who seals the nomination. Because we all know that any non-GOP candidate will certainly be the spawn of Satan
