As I have stated before, she and those of her ilk are merely the D's Tea Party.
At least on the face of it early on, that seemed to be the case. What seems to be interesting is this group is they seem to be driving the party to the left. Many of the 147 D candidates for pres seem to be echoing a lot of their ideas. I also get a strong sense that VOC and some of her ilk are starting to annoy some of the D leadership, which ultimately could lead to their demise politically. Say what you want about Nancy Pelosi, but she still wields a lot of power.
Moving into the 2020 race, I see a lot of jockeying for position with everyone trying to veer farther left and out left everyone else. They need to remember that Joe Sixpack voter is not the dude that elected VOC into office, you have to play to the masses in flyover country, the left is going to win in NY, CA, etc., areas where these leftist ideas play well, but those states don't determine national elections. Personally I think the left are setting themselves up to fail. They still don't understand why Trump is president, and continue to do everything in their power to see that he gets elected again.
