5 things to watch in the vice presidential debate

Trump’s taxes are the single most effective attack line Clinton’s campaign has against him in the homestretch, a slow-motion scandal akin to her slow-drip email nightmare. His refusal to release the returns — and his ill-considered blurt that he was “smart” to avoid paying at the first debate was followed by a bombshell of sorts: The New York Times was leaked portions of his 1995 tax return showing that he lost nearly a billion bucks on his lousy casino and real estate deals.

.. If there’s any pressure on Kaine, it’s that he has a reputation as a very good debater, a point my colleague Anna Palmer made recently, evidenced by his cool dismantling of opponent George Allen in the 2012 Virginia Senate race.

.. Despite his nice-guy rep, Kaine has a mean(ish) streak, and has no problem going negative. His somewhat awkward convention speech featured a game, if not quite Alec-Baldwin-quality imitation of Trump, and his stump speech is peppered with attack lines.
