IMO this is a Pyrrhic victory for the Dems. Lamb ran and apparently won as a centrist Democrat. This throws a monkey wrench into the Bernie wing of the party with their claims that the party has to lurch even further left. So the Dem civil war will continue unabated and unresolved.
I don’t really see it that way. Democrats lie about their agenda. They get caught after passing some power grab, get tossed out, rinse and repeat.
