The opposite of Democrat is not Republican. But opposing the Democrats often requires supporting the Republicans.
Yes, the Republicans suck but at least there’s a strong limited-government contingent. Even if it fails to live up to its own standards, the Republican party at least acknowledges that government should be limited in its scope. And need I point out that without Republicans, the Second Amendment would be long gone?
There is no small government group among the Democrats because there is no principled limit on the power of government within Progressivism Regressivism. There may be individual policies where Regressives choose to limit government but as far as I can determine, those do not derive from principles, just political choices. There is a big difference.
Yes, the Republicans suck. But they suck a lot less than the Democrats.
