New York, Nov 6 (IANS): US Republican nominee Donald Trump, who has long suggested without evidence there is voter fraud in the US, explicitly accused Democrats in Nevada in engaging in the practice, a media report said.

Speaking in a convention centre hall in Reno, Nevada, Trump alleged that the long lines in Hispanic neighbourhoods on the last day of early voting in Las Vegas were the result of the machinations of "crazy broken Harry Reid and his political machine", referring to the Senate minority leader, who hails from the state, the Guardian reported on Sunday.

"It's being reported certain key Democratic polling locations in Clark County were kept open hours and hours beyond closing time to bus and bring Democratic voters in," Trump alleged.

He added, "folks, it's a rigged system, it's a rigged system" to loud boos, before insisting, "we are going to beat it".

On Friday alone, 57,000 people in Clark County, which is home to Las Vegas and majority of Nevada's population, voted. In total, over 770,000 votes have already been cast in the swing state, making up roughly two-thirds of the estimated turnout, and Democrats are widely favoured to win the state, unless there is record Republican turnout on Tuesday.

The Republican presidential nominee also mocked Obama for suggesting "Donald Trump is hurting the foundations of our country by talking about rigging the system". He added dismissively, "give me a break", and called Obama "a phony".
