If the e-mail matter were the only blot on Hillary's public record, most folks would give her some slack. But the revelations of how things are bigger than she said they were bring a "This, again?" response from lots of folks, including folks who aren't real political.

Trump is Trump is Trump, but he was elected in competitive primaries. Hillary, however, had the deck cleared for her by the DNC; it took a non-Democrat Socialist who was an outlier to provide a credible challenge to Clinton's nomination. The Democratic Party cleared the decks for a sleazebag. Since Bill will come back as the First Gentleman, that will make it two (2) sleazebags. When a party can nominate a candidate with basic integrity and blocks that for Clinton Redux, what does it say to John Q. Public?
