They had optioins. Status quo Joe was one, and flawed, and the less than rabid support for Joe must prove something. PAC, corporate, and big donor Money and inner party endorsements proved inadequate; the candidate was what voters perceived and to which they reacted - with a collective yawn. The Iowa folks identified more with South Bend than with Obama's legacy or Minnesota's Senate
AKlo, an honest civil servant, nonetheless had to see her effort fading. She trailed both the little McKinsey man and ol' Joe among the Republican wing of the Democrtic Party; not making 15%.
Of the three crypto Republicans, she held more promise while sitting on a super secure Senate seat in any event. Joe lost big time. Bernie and Warren each did okay in a state few view as a bastion of progressive thought.
New Hampshire will be its separate story. Biden hangs onto the gambling state's turnout hope. Then onto South Carolina with its Dem inner party set ways; while never delivering a win in the general election, to where it rightfully should be discounted as unrepresentative of any real final value to the convention nominee. No l win that state in the general, come hell or high water.
What we know now - Andrew Yang should stay in. His guaranteed income proposal is now voiced ahead of its time, but robotics marches on, jobs disappearing via that march. In Minnesota, the robots will take over the iron range, the real robots, not just the likes of Stauber and Bakk. The brigands on the range will remain. The work will be robot progress, human whining, until Yang's idea takes hold as sound mid-21st Century reality. Then they'll get in their boats and fish while getting the Yang money. Snowmobiling and ice fishing in winter. In Iowa, robot machinery and labor will farm, with fewer places to fish than land of 10,000 lakes.
