First of of all, the GOP is the movers and shakers and the sheep, mostly sheep, who don't understand much of anything and can easily be told to believe something, they think AOC is stupid, because they have been told to think that.
Then there's the puppet masters, AOC terrifies them, because she says what a lot of people are afraid to say, that a top tax bracket should be over 70%.
This is what the US had, during it's period of greatest growth, it's what Japan had during it's period of greatest growth, it promotes a fairer distribution of wealth, a robust middle class and economic growth.
In Russia, they started out with a 30% top tax bracket, they have a huge disparity in wealth distribution, a middle class that is suffering, low growth and they are trending away from democracy towards autocracy. (The GOP goals for America, but they don't tell the sheep that)
AOC will tell the sheep that, and some of them might listen and wise up.
And that's what scares the shepherds and leads them have the sheep attack AOC at every opportunity, because if she catches on, the GOP is gone.
On climate change she is correct, we have to act and we have to act soon, or the world as we know it is over.
That's another the Masters don't want the sheep to hear.
