Yes but it is not just them. It goes right down to your city and county.
ATM, republicans are the worst but they are by no means the only.
As I have said before, voters can have anything they want. R and D are in the business of staying in business, if voters want candidate who wear pink tutus then that is what the parties will offer. Same goes for honesty and actual working for the people.
If every single republican lost their election in the midterms you better believe the GOP would reform so fast it would make your head spin. Same with Dems in the election after that. In fact, we are starting to see that with the Dems. Not the party so much yet but with the voters.
A lot of reform is just changing the disinformation message. Remember the Obama fake birth certificate? You are always gonna have 25-30% of the supporters for either party buy into sh1t like that. It only takes 51% to win an election. You get half way there just by tricking the blindly loyal. They don't even know they are blindly loyal too.
