The Comey reversal will reverse some of this graph
Not really. Over for Hillary.
I doubt it.
The people who made up their minds are not going to be influenced by what Comey did.
The few undecided have as much chance of seeing it as confirmation of the lawlessness in our government, rather than as vindication of Hillary Clinton. Probably a greater chance.
Hillary's rabid supporters undoubtedly see it as vindication, but they think she's never done anything other than fight for children and the downtrodden.
