’16 AT 30 THOUSAND

On this news filled Friday, we here at The Lid want to point your attention to something that may have gone a little under the radar: tonight’s Democratic presidential forum hosted by msnbc’s Rachel Maddow at 8 p.m.. It is true that the field is not as volatile as the GOP side, but that is exactly what could make tonight so interesting. Hillary Clinton has doubled her lead over Bernie Sanders, according to the latest NBC News/WSJ poll. Sanders, in turn, has ratcheted up the rhetoric."I disagree with Hillary Clinton on virtually everything,” he said recently. Also this week, Sanders said there were “valid questions” about Clinton’s email usage and suggested that her inconsistency on issues like the Trans-Pacific Partnership agreement "does speak to the character of a person." Though they won’t be on stage together tonight, there still may be some fireworks.
