I doubt it. There's still a long way to go. Americans forget shit.
The best that happened yesterday is maybe some Bernie supporters switched over, and I say maybe.
Personally, I support Sanders because I like his ideas and I agree with him that the Democratic Party needs to reinvigorate its grassroots support to ensure its continued health and electoral viability at all levels of government. I hold no special animus towards Hillary Clinton, and I am glad she performed well at the hearing. I imagine most Sander's supporters feel the same way.
Is there lingering distrust over her Iraq war vote, financial ties, and connection to forces that pulled the Democrats to the right in the 90's? I would say yes, but no more than is directed towards any other Democratic politician with those connections, and there are many. Despite the visibility of some vocal supporters online, I imagine the vast majority of Sanders supporters would vote for Hillary in the general. If they were not already planning to do so, Hillary would be far behind in the national polling.
I just hope this is the end of the hearings because the GOP realizes they look bad for them. What I don't want to see is a prospective Clinton canidacy and presidency that turns into a faux scandalfest like what happened in the 90's. That possibility would be bad for the country and the Democratic Party because, like the 90's, it would suck all the oxygen out of the room for addressing other issues. Somehow, President Obama has managed to avoid this, despite all of the other invective and obstruction Republicabs have hurled at him.
