I hope she isn't, especially as she would be one of the worst Democrats we could put up should Biden actually win.
But she probably will, and I wouldn't be surprised if it ended up being like Al Gore's run in 2000, meaning no other serious candidate runs, except for one sacrificial lamb from the party's left flank, like Nina Turner.
I see it as more like 1968. A few notable dems will challenge her, but there is still enough institutional support to keep the VP ahead.
Hopefully it won't be like 1968 in the general election.
