But if the GOP actually increases the size and scope of the federal government faster than the democrats or any other party, then why would they continue to vote Republican.
Republicans (in their current manifestation) also won't defend the southern border any better than the democrats. They also won't defend property rights. The won't defend freedom of speech either (CFR).
Anti-abortionists aren't going to vote Democrat, nor are they going to vote third party, for reasons I have already told you.
