Trump et le vote secret: sous-estime-t-on les chances du candidat républicain?

Il y a des électeurs qui n'avouent pas ouvertement qu'ils vont voter pour Donald Trump et les sondages ne le refléteraient pas. Un risque pour Hillary?

 "“I'm not sure how big a factor it is, but there is definitely a ‘Bradley effect’ going on out there,” said a Virginia Republican, referring to the African-American mayor of Los Angeles who led in polls but lost unexpectedly in the 1982 California gubernatorial race. “I personally know many Republicans that won't admit that they are voting for Trump. I don't like admitting it myself. It won't matter if Hillary is up more than 5 points, but we might be in for a surprise if Hillary's lead is less than 5 points on Election Day.”"
