Hillary is the Uniparty candidate.
I've always maintained that the Republican elites have more in common with the Democratic elites than they have with the grassroots voters who they swindle for money and votes every election cycle. Democratic and Republican "leaders" and "spokesmen" play-fight with one another over hyped-up non-issues, but they march lockstep together on issues that really count.
The GOP elites who now openly support Hillary have finally proved this point beyond a shadow of a doubt. The rest of the GOP establishment is mostly thinking the same, but they have the political skills to keep quiet about it.
