No doubt she knew he was a walking (wobbling?) potato.
But in her defense (and I’m not AT ALL defending HER, per se)... don’t you think the optics of the sitting VP leading the charge to dump the POTatus would have been political suicide?
You are correct. But Harris knew years ago that Biden’s senescence put the US and the world at risk, yet she put the effects ON HER of doing something about it above the public good. If it’s unfair for her to be in a lose-lose framework ... what a shame; she chose it going in.
Trump should be able to destroy Harris with this:
1) If Harris didn’t notice Joe was senile, that confirms that she is a complete idiot.
2) If Harris did know, she failed to act responsibly to protect the nation and world.
3) If Harris tried to cover up Joe’s mental and physical decline, she did a very poor job of it, as we’ve come to expect.
