Ive been looking, but its hard to find. The 2 Im listening to right now are
Keepin it 1600 - Former Obama speech writers. Hate the GOP and aren't shy about it. However, they alway frame the stories to what they're experiences were working for Obama during his election and re-election. Some really cool behind the scene stories.
FiveThrityEight Elections - Looks at the race from statistics POV. Very into polling and what it means, and take much more analytical approach. They lean left too, but try to be more objective in their analysis.
