LONDON, November 7, 2016 /PRNewswire/ -- More than half of Republicans will blame the media if Donald Trump loses on Tuesday, according to new research from British pollster Lord Ashcroft. Asked what would be the most likely explanation if the result went against them, 54% of Republicans chose "the media has worked overtime to undermine the candidate you supported". A further 25% said they would blame "a systematic effort by the authorities to rig the outcome". Nearly half (49%) of Democrats said defeat for their preferred winner would mean "another candidate has won fair and square in a tough but above-board election"; only 21% of Republicans chose this option. And in an echo of Donald Trump's campaign rhetoric, 54% of GOP supporters strongly agree that "reporters who knowingly write false stories should face criminal penalties", compared to 32% of Democrats.

While Republicans are more likely than Democrats to believe that "if you work hard, it is possible to be very successful in America no matter what your background", they are much more likely than Democrats to say that "for most children growing up in America today, life will be worse than it was for their parents", that changes in society and the economy will bring "more threats to my standard of living than opportunities to improve it", and that "life in America is worse than it was 30 years ago".
