There are quite a few of them but the ones progressives have a stake in, in chronological order, are Hawaii (August 9), Wisconsin (August 12), and then a late super-Tuesday on August 26 for Arizona, Florida and Oklahoma. That same day has primaries in Alaska, Missouri, Oregon and Vermont with interesting races but no races that pit a progressive against a shill from the Republican wing of the Democratic Party.
Up top is the brand new video from one of the most grassroots campaigns anywhere, the Tom Guild campaign for the open Oklahoma City congressional seat. Guild came in a strong first in the 3-way June 24th primary, beating non-courageous, and conservative Establishment Democrat Al McAffrey:
• Tom Guild- 11,597 (42.1%)• Al McAffrey- 8,505 (30.9%)• Leona Leonard- 7,424 (27%)
