I had mixed emotions about Biden running, but I was leaning more toward hoping he would in the event Clinton's emails/server investigation blows up in her face. I wanted Democrats to have another viable candidate other than Bernie, who I like, but who I don't believe is ultimately electable. My friends who support Bernie disagree, I know, but some of these same folks assured me that a vote for Ralph Nadar was vote of conscience and wouldn't hurt anybody. BTW, I think the emails/server investigations could blow up in Hillary's face even if there is no there, there. The appearance of something there is all it could take. I personally don' think there is any there, there, and I don't find it odd that she used her husband's server. That her husband had his own server really doesn't surprise to me: he is a former president and still politically active.
Sure, I'd like to see the first woman president, and I was ready to support Clinton wholeheartedly this time around, after supporting Obama in 2008, but then the email/server controversy raised its ugly head, and I suddenly remembered how good the Clintons are at giving ammunition to their enemies, (and, yes, I'll use that word) and suddenly I had Clinton fatigue.
