Not quite.

The Republican party may DESERVE to be abandoned, true, but it is currently the only organized "opposition" to the Democrat party that exists on a large enough scale to be effective. While the Republican party may not be doing its job of protecting America, the Democrat party is is doing its job of DESTROYING America all too well. On top of this, the Republican party is a symbol for the normies, one which they will be much more willing to rally around than a new third party.

With that said, the solution is for us to TAKE BACK CONTROL OF OUR PARTY - kick the RINOs out if we can, ostracize them and make it clear that they aren't being re-elected (and thus have no real power) if we can't. I don't know how we can accomplish this within the time frame it needs to be accomplished in, but it NEEDS to be done - if our army languishes under the command of inept and corrupt officers, the solution is to replace those officers, not to disband the army and allow our enemy an easy victory.

The left seized control of the media, the courts, and even much of the Republican party by targeting key policymakers and influencers with threats, bribery, blackmail, intimidation, and, when necessary, assassination. Each of these individuals holds sway over thousands of Americans and their votes, if not more, which means that a single instance of bribery/blackmail/etc allows Soros and friends to influence thousands of voices and thousands of votes.

While I would never encourage anyone to break the law, I can't help but wonder if the left's stranglehold on the aforementioned institutions could be broken through the application of opposing pressure on those same key individuals. Currently, bowing to the will of the left brings them wealth, power, and safety, with no real downsides, but what if that wasn't the case? What if shoving leftist narratives down everyone's throat wasn't a clear, easy, and safe path to wealth? What if obeying Soros wasn't a guarantee of safety, and going against him a guarantee of harm? What if the normies weren't force-fed a diet of 100% leftist propaganda day in and day out?

I'd say that a change in THAT state of affairs would accomplish a LOT more than protests against the compromised courts and legislature (not that the two are mutually exclusive). Though, of course, you absolutely should NOT resort to any sort of illegal activity, despite the fact that your opponents completely disregard the law. Keep it legal!
