Nonsense.
NH Democrats #s 1, 2, 3, and 4 issue was beating Trump. It's all they talked about, they've been frantic about it on Facebook and in public for weeks.
You can't sit in a diner or go get coffee at work without hearing it.
Amy Klobuchar, who campaigned here as "Amy", came in third after all. But she was the unity choice of Dem voters who a) Couldn't vote for Bloomberg because he wasn't on the ballot, b) Know in their rational mode that neither Bernie Sanders or Mayor Pete is going to be the next President, and c) Preferred "Minnesota nice" over the two weirdos Biden and Warren.
In their minds, the people are going to turn against Trump because he's not nice. Who knows, that may even be true.
But none of this matters, because Bloomberg is the nominee and they all know it. After the fantasy votes for Sanders and Pete, "Amy" was the voters clear choice for VP.
It's not more complicated than that.
