The hard left’s takeover of the Democrat crime syndicate has put them in a position where their “leader” may NOT be a heterosexual white male. “It” must be one or more of gay, trans, minority, enviro-whacko or woman. No exceptions.
Not just leadership. Membership, period.
In the last election my brother voted Libertarian (Gary Johnson). While he dislikes Trump, there is no way he will vote Democrat.
I predict many, if not most, white straight males will leave the Democratic party. Why stay there among such hostility? Instead, they'll either defect to the GOP or, if they actually want to remain liberal, hook up with the 3rd parties like Green or Libertarian.
Probably anyone with a modicum of mental health, white or otherwise, will leave. The only ones left in the Democratic party will be fringe -- feminists, gays, and underclass minorities.
