Only one of Hillary Clinton's campaign staff had warned her about losing the presidential elections despite polls showing her in the lead, according to a report in Politico. 

Jake Sullivan, Clinton's chief foreign policy director, had warned her about the defeat and counselled that she visit swing states before election day. However, other members of the campaign suggested that she visit Texas or Arizona for good press. 

Sullivan was the only aide to advise Clinton to spend time in Midwestern swing states before the election. 

Ignoring his suggestion cost Clinton the election. Donald Trump won with 290 electoral college votes even though Clinton got the popular vote. 

Clinton had been projected to win by almost every national poll, including hers and Trump's. 

"Sullivan, a brainy and nervous former State Department aide who took on an increasingly important political role as the campaign ground on - was the only one in Clinton's inner circle who kept saying she would likely lose, despite the sanguine polling," Thrush wrote, citing Sullivan's friends.

"He was also the only one of the dozen aides who dialled in for Clinton's daily scheduling call who kept on asking if it wasn't a good idea for her to spend more time in the Midwestern swing states in the closing days of the campaign."

Clinton had flown to Republican-leaning Arizona one week before the election to ensure they voted for her. 

Her friends had also warned her early on to not fight the presidential elections twice in a row. 

The FBI reopening an investigation only 10 days before the election over emails she wrote while she was the secretary of state also harmed her campaign. The FBI later had said that they found nothing substantial and would not be charging her, but the damage was already done. 

Clinton has recently been photographed doing everyday things with husband, former president Bill Clinton, and seems to be enjoying a downtime after the madness of the election campaign.
