@ feola This is no all-or-nothing decision. As far as I’m concerned, it’s a matter of pragmatic objectives, focus, and (in time) results. Personally, this Forwardist is a card-holding Libertarian who supports ANY party’s campaigns on a case-by-case basis, depending on if it advances my causes (minimization of government, decentralization, and maximization of personal freedom; whether that’s in ending wars/war-involvements, nullifying unjust Federal acts on a State-level, cutting budgets, ending qualified-immunity, protecting the Bill of Rights, etc.) or not.
And as may be noticed: With the absence of other major-parties, the duopoly-members have changed both within our lifetimes & in much-longer U.S. History. Party-leaders’ proprieties, campaigns, and actions are bound to neglect, marginalize, even outright abandon certain causes, depending on happenings of the day (overall state of the 2-party rivalry, palace-intrigue, positive/negative media-coverage or lack thereof, who & what party’s in power at the moment). PERSISTENCE is a must, REGARDLESS of who’s in power, what their priorities of the day are/aren’t, what mainstream media & party-leaders dictate, and the like.
For example, we Libertarians in the non-party Tenth Amendment Center have been pushing States to remember their long-lost, Federally-usurped power, and have received much “extremism”-flack for more than a decade, under Republican & Democratic rule. But NOW, then-“extremist” nullification has become so mainstream, it’s being used by the Left & Right (State-legalization of marijuana and/or raw-milk, countering Federal gun-rights restrictions, countering local police-militarization, limiting qualified-immunity, Defend the Guard, etc.) without 2nd-thought. Could this have happened if we depended solely on 1 party? lol NOPE! WE had to do it.
We helped allies when they existed (depending on campaign), and continued even when alone. Persistent pressure over the years gave us victory. So, depend on mainstream party-leaders? lol The Republican party-leaders “supported” us Libertarians when we proved useful, stopped pretending, then kicked us out afterward. Democratic counterparts kicked their own ideologically-consistent Bernie Sanders in the gut, how did they treat their own anti-war Tulsi Gabbard, and what “support” did they give their own reformer Andrew Yang? Even if they “support” our cause now, what do you think they’ll do as soon as it ceases to prove useful to them?
Hence, diversity, and support cooperation. That way, even if any 1 fails, the others can keep pushing.
