Thousands of Bernie Sanders supporters are marching down a main thoroughfare in Philadelphia to show their support of him and disdain of Hillary Clinton ahead of the Democratic National Convention.

Chanting “Hell No, DNC, we won’t vote for Hillary” and “This is what democracy looks like,” the marchers headed from City Hall down Broad Street. Broad is the main north-south artery that leads from downtown to the convention site at the Wells Fargo Center about 4 miles away.

Many carried Sanders signs, and a huge Bernie Sanders puppet was also a part of the march.

Sweltering heat hasn’t kept protesters away from the streets Sunday. The city is under an excessive heat warning and temperatures were in the high 90s.

The four-day convention for Democrats to nominate Clinton for president begins Monday.
