Hillary Clinton has surged past Donald Trump in nearly all post-convention polls, including a double-digit lead in the latest Fox News poll, which shows the former Secretary of State trouncing Trump by a whopping 10 points.

Trump briefly led Clinton following the Republican National Convention in July, 45.7% to 44.6% according to the RealClearPolitics average of polls.

That lead evaporated, however, immediately following the Democratic National Convention a week later, catapulting Clinton to a 5.1 edge over Trump. Including only polls conducted after the DNC, Clinton’s lead grows to 5.3.

Trump’s odds of winning in November have plummeted following the shift in the polls, with Nate Silver of FiveThirtyEight downgrading Trump’s chances from 50.1% to just 26.7% according to the polls-only prediction index.

Other political prognosticators gave similar odds, with the New York Times giving Trump a 25% chance of winning, while PredictWise gives the GOP nominee just a 23% chance of beating Clinton.

The Princeton Election Consortium’s poll-based prediction index is even more bearish on Trump’s chances, giving him just an 18% chance of winning.

On Monday, Trump warned the upcoming election could be rigged, touching upon a theme of his campaign for the Republican nomination, which Trump suggested the RNC may be aiding his GOP opponents.

“I’m afraid the election’s going to be rigged.”

"I'm telling you, November 8, we'd better be careful, because that election is going to be rigged. And I hope the Republicans are watching closely or it's going to be taken away from us."

Trump’s comments came following leaked emails from Democratic Party officials showing the DNC actively worked to deny Bernie Sanders the party’s nomination and ensure a win for Clinton.
