He was good for the strategy she had. The problem was it was the wrong strategy.
Exactly.
Also - wasn't the general consensus in this forum that VP's barely move any votes?
I think this is absolutely true that the
VP candidate themselves doesn't generally impact election outcomes, although it can potentially flip a state sometimes....
There is
one obvious exception----1960- Kennedy picking LBJ was the difference between a win and a loss.
If we look at where the VP impact might have changed outcomes in particular states:
1968: Humphrey picking Muskie might well have won him Maine in '68, Nixon picking Agnew might have made Maryland closer than it otherwise would have been (IDK--- the Wallace vote probably played a larger factor there).
1980: Reagan picking George HW Bush probably made the difference with him snagging Mass & Maine
1988: George HW picking Quayle might have had enough of rural bleed-over into Illinois to make the difference
However---- where I think the selection of a VP candidate does make a difference is in much less obvious ways. This is one of the most watched decisions that the party nominee makes, at a critical time in the campaign season.
McCain's selection of Palin helped reinforce a narrative that he had a tendency to shoot from the hip and was prone to "going on tilt" hence casting concerns on his judgement under pressure, and occasionally making irrational decisions.
Granted, this certainly was not the deciding factor in the 2008 election, where American's were suffering from seven years of war wariness, combined with a catastrophic economic collapse wouldn't have likely made much of a difference. McCain suspending his campaign to fly back to DC in what was widely seen as an erratic move reinforced the image of the candidate.
So, generally Presidents select their VP based upon balancing out the regional coalitions, reaching out to elements of the party in contested primaries in order to create party unity and the like.
Trump's selection of Pence was a traditional classical selection.... someone with immaculate pedigree in the eyes of the Christian Conservative wing of the Party, who also happened to be from the Midwest. He chose not to go with more of a Kasich or Rubio style Republican, that in the primaries performed extremely well in high-income precincts/counties.
Clinton chose to go with a Governor from Virginia, even though she had been hammered during the primaries by both Sanders and Trump as representing standard "Washington insider politics".
So here, Trump was actually quite successful at holding the evangelical base of the Party, plus chipping off a significant number of Obama 1x/2x voters in rural and small-town areas.
Clinton's VP choice was not widely received positively by the Bernie wing of the Party, let alone many independent and even some Republican voters. The optics of the Kaine selection and then later the DNC hacked emails, reinforced an image/stereotype of Clinton as a Washington "insider".
Yes--- VP choices rarely can be directly correlated to Presidential Election outcomes.
However, the choices that a candidate
does not make somehow with historical perspective, can potentially have played a bigger role in the outcomes than the decisions that they did make.
