Most conservatives hope the polls showing Hillary ahead are wrong. The Bradley Effect is sometimes cited, because many potential voters might not want to admit to a pollster that they plan to vote for Donald Trump.
But with the drip, drip of negative news releases revealing Clinton's ineptitude and/or duplicity, one has to wonder why anyone would consider voting for her. Obviously there are those who do and are willing to admit it. But there must be plenty who want a progressive president but who couldn't admit they wanted Hillary.
She is as likely to benefit from the Bradley Effect as Donald Trump.
