Reply #82: Of course electability is a key issue.

The operative word here, I believe, is "Duh."

Many of the currently unpledged delegates are elected officials, many of whom are seeking coat tails to ride in November. You also have a number of Senators who don't wish to create bad blood with either candidate. The rest are DNC members who are remaining unpledged for any number of reasons (wishing to remain impartial, seeking to get a cushy White House job/ambassadorship, etc). The remainder are Florida and Michigan delegates, who are irrelevent.

How this translates into a groundswell of SD support for Senator Clinton is the real mystery. You are making the assumption that your candidate is the only one who is electable. It's a mighty big one.
