Are you are having trouble with comprehension tonight? Bill Clinton won because of lot of people drank the Perot koolaid. Not me -- I supported and worked for Bush and then Dole in 1996 and Dole was not my first choice by a mile but I did like Jack Kemp.
Losing is not an option a campaign considers when running a candidate unless you support someone that doesn't have a chance to win because their support never gets about 2-3%!
The problem with your viewpoint, that the only thing that matters is that a candidate with your party's letter beside his name wins, is that much more important considerations are put aside...questions that go to whether they're worth electing in the first place. It really doesn't take a rocket scientist to figure it out.
Y'all have the cart so far out in front, it's going to go over the cliff about an hour before the horse.
