Elizabeth Warren's record of dishonesty will haunt her

Caught in another lie, this time about how her public school teaching career came to an end, Sen. Elizabeth Warren risks giving voters the same reason to reject her as they did Hillary Clinton four years earlier: a decades-long pattern of dishonesty and shape-shifting false claims.

Warren seems to hold the hot hand right now in the Democratic presidential race. Some recent polling shows her surging to the lead in both Iowa and New Hampshire, edging ahead of former Vice President Joe Biden. She attracts Trump-sized crowds to her rallies, sticks around for hours afterward to take pictures with adoring fans, and seemingly has a detailed plan for every problem, from skyrocketing college debt to the opioid crisis.
