Donald Trump and Family Preview Path to Victory

— -- Donald Trump said that he expects to win the key battleground states of Ohio, Florida and North Carolina -- victories he says will help push his campaign over the finish line.

"I think I'm gonna win," Trump told ABC News on Wednesday.

Trump and his family gave their take on the final stretch of the presidential race in an exclusive interview with ABC News' George Stephanopoulos in their new hotel in Washington, D.C.

Donald Trump said that he intends to spend heavily in the final days of the campaign. The real-estate mogul said he is prepared to pour in $100 million of his own cash on the campaign by Election Day.

When Stephanopoulos noted that Trump has spent $56 million so far on his campaign, the Republican presidential nominee said, "Well, no, it's $61 million. But I'm spending a lot of money. And that doesn't include everything. I'm spending a lot of money.”
