Trouble is brewing on the road to Hillary Clinton’s coronation.

Fans of Bernie Sanders who believe the primary system is rigged against his candidacy are taking their fight to the convention.

Organizers are vowing to have one million dissenters attend the Democratic National Convention.

“WE’RE READY TO GO! Our goal is 50,000 new members ASAP and 1 MILLION STRONG TO THE CONVENTION! Everyone add as many Bernie supporters as you can to make this happen — nothing more important than 1 Million strong!” organizer Laurie Cestnick wrote in the “Occupy DNC Convenion” Facebook group, which has over 18,000 members and is growing.

They’ve set up a PayPal account and are accepting donations to fund their activities.

Meanwhile, other Bernie supporters have secured permits to hold protests near the convention site.

NBC 10 reports:

The four rallies, given permits Wednesday night, bring the total to five for approved rallies and marches during what is expected to be a bustling week of political activity in Center City and South Philadelphia. The convention officially runs July 25-28, but two of the five approved rallies and marches of more than 7,000 activists will be held July 24 — the day more than 4,000 delegates arrive from across the country.

The permits allow some 30,000 people to attend the “March for Bernie at DNC” rallies, but if Cestnick has her way, there will be a lot more than that.

“The goal is to swing super delegates to vote for Bernie. We are showing that HE is the will of the people NOT a fraudulent Hillary nomination,” Cestnick says in a document on the group’s Facebook page.

“So, we are contesting Hillary’s nomination on the grounds of fraud, voter suppression, and corruption. We show them who we want. If they nominate her anyway, we show them they did not ‘win’ for we will not be voting for her in November,” she writes.
