75. Not true

Clinton's attempts to reach across the aisle and achieve bipartisan consensus - which is just a euphemistic way of saying pander to white racists - did not work. That's the lesson of the Clinton era. Trying to win over "white working class voters" - white racists - is a losing proposition and always has been.

From the article:
