It's pretty easy.
List the top 10 problems that this country faces. If it's hilariously inane bullshit like CRT, Covid Vaccines, Social Media "censorship", etc, then you're a Republican pretending to be an Independent and can be safely ignored.
If it's real, actual problems like climate change, healthcare, renewable energy, etc., then list 5 fucking Republicans who have any serious ideas to actually address any of those problems, besides just saying "tax cuts" and "deregulation". Hint: they don't fucking exist.
And if the Democrats solutions are "too extreme", because the problems aren't that bad, well guess what, that's the whole god damn point of US Government being tied in knots and unable to "do things", because hey, fuck it, the problems aren't that bad, it's better that nothing gets done.
In other words, The FUCKING DEMOCRATIC PARTY IS THE BIG TENT PARTY ALREADY. You have Manchin and Sinema and Ocasio-Cortez. That's the full fucking gamut of "identifies problems and puts forward solutions" right there. The Republican Party only gives a fuck about tax cuts for the rich and scaring their base into believing wildly hilarious delusions that their propaganda networks push out over TV, Radio, and Internet. i.e. COVID vaccines are for a hoax disease that is also a Chinese Superweapon or whatever nonsense they can believe and disbelieve at will because that's how they've been trained to believe for going on 40 years now.
RadicalIndependent™ is here to push one agenda: BothSidesDoIt™. The BigLie that allows the Republican Party to continue skullfucking this country to death for a few oligarchs' couch cushion change.
