Democrats just raised military spending to new heights, refused student loan forgiveness, enabled draconian lockdown laws, pushed the USA close to a nuclear conflict with Russia, created the highest inflation in US history, open borders, pushing censorship for science, supporting regime changes throughout the world, etc. The uniparty has different talking points to dazzle smoothbrains but actual policies are identical.
When trying to show that democratic politicians have moved as far to the left as republican politicians have moved to the right the response "they both do the same policies" isn't an argument. We are talking about state level politicians on the republican side putting out laws to reverse marriage equality, disallow trans people from bathrooms, and define treatment of trans kids as child abuse. If you have examples of the democratic state politicians doing things that are crazy left in your mind to counter there examples that would be interesting but I assure you "it's all one uniparty" isn't really a response as these bills are not being passed by democrats. Like Rol said I think a lot of people who argue that the rhetoric is the same on both sides are comparing the twitter left to actual republican politicians with power.
