Trump says Republicans being 'naive' about voter fraud

Donald Trump lashed out on Monday at Republicans who have tried to tone down his rhetoric about election fraud, calling his party's leaders "so naive" and claiming without evidence that large-scale voter fraud is real.

Trump's claims were part a Monday morning blast of tweets that took on his party, the women who've accused him of sexual misconduct, the media and Vice President Joe Biden.

The defensive barrage, interrupting a relatively quiet day on the campaign trail, comes as Republicans are under pressure to rebuke Trump's claims that the presidential election is "rigged" in Hillary Clinton's favor. The push reflects growing worries that their nominee's unsubstantiated rhetoric could erode public trust in elections and lead to damaging disputes if he loses.

Trump's running mate, Mike Pence, declared Sunday the ticket will "absolutely accept the results of the election." But Trump seemed to brush back against his vice presidential pick.

"Of course there is large scale voter fraud happening on and before election day. Why do Republican leaders deny what is going on? So naive!" he tweeted Monday.

There is no evidence to back up Trump's claim of widespread voter fraud. A study by a Loyola Law School professor found that out of 1 billion votes cast in all American elections between 2000 and 2014, there were only 31 known cases of impersonation fraud.

Pence and other Republicans have tried to argue that Trump is claiming that media bias is rigging the election in Democrats' favor, particularly in the reporting of allegations by several women that Trump had sexually assaulted them.

Trump pushed back against those women Monday, tweeting: "Can't believe these totally phoney stories, 100% made up by women (many already proven false) and pushed big time by press, have impact!"

In another tweet, Trump linked to a video montage of Biden greeting and hugging women at various events. The Democrat has not been accused of sexual improprieties, but has raised eyebrows for his lingering or awkward embraces of women.

The tweets abruptly returned the focus to the Republican candidate's list of troubles on an otherwise quiet day on the campaign trail ahead of the final presidential debate Wednesday. Trump is spending much of day out of sight before campaigning in Green Bay, Wis., Monday evening. Clinton is slated to spend Monday preparing with advisers near her home in New York.

As the candidate prepares, Clinton's campaign continues to have to answer for the contents of hacked emails being released by the thousands by WikiLeaks. The most recent batch showed Clinton generally avoided direct criticism of Wall Street as she examined the causes and responses to the financial meltdown during a series of paid speeches to Goldman Sachs.

WikiLeaks said Monday that founder Julian Assange's internet access has been cut by an unidentified state actor. Few other details were immediately available.

The fraud concerns raised by Trump aren't new to Republicans. They often cite the risk of fraud as they make a case for tightening access to the polls through voter identification laws and other restrictions. But Trump's often repeated claim that the election is "rigged" as put the party in the unusual position of expressing faith in the legitimacy of the election system.

Leaders in both parties fear Trump's claims will encourage his most ardent supporters not to accept the results, leading to prolonged litigation, possible violence or hardened divisions — or some combination of the three. That could make it even difficult to govern and take a long-term toll on the democracy.

Even staunch conservatives have found themselves in the position of trying to gently walk back the nominee's remarks.

"I just don't think it's that constructive to make this a campaign issue," Rep. Steve King said Monday on CNN. The staunch conservative from Iowa said he shares Trump's worries about election fraud, but acknowledged Trump's claims are "partially unsubstantiated."

"I don't want to say anything on this program that delegitimizes our election," King said.
