This is true. We've had a Uniparty for decades now with a lot of Kabuki Theater pretending that the Democrats and Republicans are not the same. Even the term Republican In Name Only (RINO) was an attempt to pretend that Republicans who clearly supported Democrats were still Republicans.
The Uniparty needs to keep up the pretense that people need government because if people walk away, they're not coming back. When votes don't matter, neither do politicians. The people will they'll rightfully demand action directly from the cause of the problem instead of wasting time wringing their hands over the "the system" and "ineffective politicians".
"This is a problem that needs to be fixed."
"Our useless and corrupt politicians will do nothing about it."
"Forget those clowns. YOU caused it and YOU need to fix this."
"We swear Lucy will help you and won't pull the football away this time."
The only reason parties exist is to give voters the illusion of choice.
That said, it doesn’t mean we can’t use the existing infrastructure against them.
As long as the vote counts aren’t rigged.
And that problem has to be dealt with first and permanently.
