Yeah, it's literally not just preaching to the choir: conservatism as political and ideological movement is failing. Notably, because each subsequent generation is more liberal about social and cultural issues (and consequently, fiscal issues.) as time moves on. But when you've literally staked your existence on the concept, and the population as a whole continually leans left, you either drag them whole towards the right, or you slide to the left.
And since modern conservatism is LITERALLY based on "winning" (as in, beating the other guy, regardless of context, conditions, and such.) they have nothing left to them except to perpetually drag the overton window to the right. They will push ever harder into fascism and authoritarianism as more and more people hear their bullshit for what it is: dated, tired and obsolete.
I mean, small government would be nice if government was competent and, oh yeah, the corporations weren't monolithic, global spanning entities intent on turning the planet to wasteland and it's population into slaves.
