The Republicans know you're not going to switch to Democrat. And they know despite everything, this is a two-party system, other parties just don't have the clout to win. Bernie got in because despite him being "Independent" he has to become a "temporary Democrat" to run so he gets party backing.
The Republicans who sold us out know unless we just want to throw our vote away we have to vote for them or a Democrat and they know we aren't ever voting Democrat. there just aren't going to be enough of us switching to a 3rd party candidate to scare them.
Not saying don't do it, I definitely am going unaffiliated but I wonder how much they will care.
I think you will be surprised. I will be voting for a Demoncrat challenger against some of my Republicucks incumbents while registering as Independent.
You are mistaken if you think everybody who has been voting Republicuck for years will do it in 2022 and beyond. What will be a shock will be how many.
