They were never going to vote for Clinton (Or likely any other Dem candidate).

I was going to say the opposite wouldn't be true (Clinton voters would have enthusiastically came out for Sanders). But then I read this section:

For example, Schaffner tells NPR that around 12 percent of Republican primary voters (including 34 percent of Ohio Gov. John Kasich voters and 11 percent of Florida Sen. Marco Rubio voters) ended up voting for Clinton. And according to one 2008 study, around 25 percent of Clinton primary voters in that election ended up voting for Sen. John McCain, R-Ariz., in the general. (In addition, the data showed 13 percent of McCain primary voters ended up voting for Obama, and 9 percent of Obama voters ended up voting for McCain — perhaps signaling something that swayed voters between primaries and the general election, or some amount of error in the data, or both.)



It looks like it's common to have these types of party defections
