It's clearly the new tactic. Their guy has been obviously senile for at least 5 years and they denied it as long as their TVs told them to deny it, despite the clear evidence of his failing mental state. Now the TV has told them it's okay to say Biden's senile as the push to install Kamala begins. There's no reasoning with these types, because they aren't basing their decisions on observation or logic, they're basing it on party loyalty. You'll have better luck convincing a Red Sox fan that the Yankees are a better team than you will convincing these people that anything the media tells them is untrue.
They don't care. Biden's mental state and age worked wonders for gaslighting the people for 4 years. Now they will try and do the same tactics that the Dems did when Trump wins. It's all about power and manipulation.
