Or, if you prefer, those who forget history are condemned to waste a lot of time and energy. Pre-convention polling data suggest that ninety percent of consistent Sanders supporters will vote for Clinton in the general election. This really shouldn’t be surprising, though apparently it is, as most Sanders supporters are just the social democratic wing of the Democratic Party–which has always existed.
But I digress. Back to the history. As it stands today, it seems like ninety percent of Sanders supporters will vote for Clinton; I expect that number to rise as Trump’s awfulness becomes evermore apparent. To put this in perspective, here’s the exit polling from 2008 (boldface mine):
In the end, Clinton bowed out of the Democratic nomination contest after the last primaries and strongly endorsed Obama. Clinton gave a powerful speech for Obama at the convention and campaigned enthusiastically for the Obama-Biden ticket during the fall. On Election Day, the vast majority of Clinton’s supporters voted for Obama despite McCain’s attempt to appeal to women by making then-Alaska Gov. Sarah Palin his running mate. According to data from the 2008 American National Election Study, 83% of Clinton primary voters chose Obama over McCain in the general election.
For those keeping score at home, 83% is less than ninety percent.
The dead-enders really aren’t worth worrying about.
