New York, August 12 (RHC)-- Former U.S. Secretary of State Hillary Clinton says her Republican rival, Donald Trump, 'may still beat' her in the run-up to the 2016 presidential vote.

In a fundraising e-mail sent to donors, the Democratic nominee reminded them that the real estate tycoon is “unqualified and unfit to lead the country” as polls showed her lead over Trump was getting stronger. But the e-mail reads: "He may still beat me. The unfortunate reality we must confront is that he still might be able to win if he spends enough to convince voters otherwise."

She further noted that Trump and his party managed to raise more than $82 million during the month of July, claiming she is the only one who can beat him.
