Not that there’s anything wrong with that!
The leftists on the comment thread at the source say "Look! The parties used to be closer together! Now one of them has changed, the Republicans!"
As if that's a bad thing.
Yes, for some time there were many RINOs who went along with the collectivism that is bankrupting us. Now that is ending.
Good!
“...it’s very much the direction of things in American politics — two parties moving further apart.”
The people have already “moved apart” - they have divided, as they always have been, along the lines of federalist vs. anti-federalist, unlimited power of the State vs. limited power, centralized Government vs local control, Rights of the Collective vs. Rights of the individual.
This shift in power has been accomplished by misusing the Judiciary, entrenched legislative and corporate interests, and bureaucratic administrative authority, without using the Constitutional Amendment process, use of which would have aired-out and resolved the true nature of the power-grab.
So, the moving apart of the political parties only reflects the unresolved differences of two factions of the people who just fundamentally disagree about the role and usefulness of their federal government.
