Bernie Sanders will not be the nominee, and wild-eyed conspiracy theories won't change that.
Bernie doesn't have the votes, plain and simple. He doesn't have the PLEDGED delegates. Plain and simple. Nothing has been rigged. Nothing has been stolen from anyone. Bernie, someone who was never even a member of the party, is BEHIND because Hillary has gotten millions more votes from voters in these primaries. It was always a long shot for Bernie, as he said himself repeatedly in the early days of the campaign.
Hillary is brilliant, progressive, and the most qualified person to run for president in recent history. She is more qualified than Bernie, who is a good man who means well but who just doesn't have her breadth of experience, especially on foreign policy.
As to assertions about Bernie being "stronger against Trump," Bernie hasn't been fully vetted at all so those arguments are baseless. If he was nominated, the R's would jump for joy and start running ENDLESS "anti-socialist/communist" ads night and day. It would demolish him. It would be a NIGHTMARE for our party. The large majority of Americans simply are not socialists.
And there you have it.
