The number of confirmed classified documents found among Hillary Clinton’s emails in a State Department review has climbed to 60, and yet she was joking about it this past weekend in Iowa. “You may have seen that I recently launched a Snapchat account,” said Mrs. Clinton. “I love it. I love it. Those messages disappear all by themselves.” But it may not be such a laughing matter for her, as there are new reports of Democrats worried about the viability of her candidacy, new polls showing Sen. Bernie Sanders (L-VT) ahead of Mrs. Clinton in New Hampshire and Iowa, and reports of Vice President Joe Biden appearing more likely than ever to enter the race as a way to try to save the Democratic Party from a potential disastrous election next year.
