Reported in The Nation, here, for what it's worth:
In 2012, 60 percent of Obama backers supported him “strongly” (the comparable figure for Romney supporters was 38 percent).
You’d be forgiven for thinking that this election has seen voter “intensity” reach new heights. However, a July poll found the level of “strong” support was about equal for both Clinton and Trump—and strikingly low: Pew found in that poll that “fewer than half of both candidates’ supporters said they backed their candidate strongly,” with 45 percent each. The equal proportions suggest intensity is not going to skew the poll results this year.
