In an interview with Chuck Todd of Meet the Press, California Democratic Senator Dianne Feinstein called upon Hillary Clinton to "step out and come out" concerning her e-mails. Feinstein added, "Silence is going to hurt her."
I think this is a fairly significant development. Feinstein is a longtime ally of Hillary. Not only did Feinstein back Hillary in 2008, she was calling upon her to run for the White House again back in 2013.
When a senior Democrat like Feinstein begins raising doubts about Hillary there's a good chance others will follow.
If Democrats don't think her release of 55,000 e-mails (none of which were on her home server) is going to cut it then she is in trouble.
