-- if she has the popular vote lead it is by definition a majority.
Yes. It is a minority that wants to overturn the pledged delegates winner. You'll note that many Hillary supporters while unhappy with the results, do want her to keep on, but will respect the delegate winner and support Obama in November.
However, there is a minority that wants to take this to the convention and have a huge fight arguing about 'popular vote' this, whether to include Michigan, etc
Most Democrats want to avoid that mess and respect the delegate winner.
And re: popular vote...Hillary is only ahead if you grant her 328,000 votes in MI and Barack 0 votes...and again, you only have a minority who wants to make that argument.
It's funny that you pick the one scenario under which she has more popular votes.
