Yes, more Clinton voters did vote-switch to Mr. McCain. That did not change the outcome of the 2008 election. The Sanders voters who vote-switched DID change the outcome of the 2016 election. Both parties sinned, but only in the latter case did the sin cause harm — catastrophic harm.
“Also, that the Sanders voters who DID switch were conservative Democrats that liked Sanders’ populist message. They were not the young progressives that form Sanders’ base.”
Do you have any data to support that?
