Could Republican nominee Donald Trump win the presidential election in November? President Barack Obama said “anything is possible” during an interview Wednesday.

“It is the nature of democracy that until those votes are cast and the American people have their say, we don’t know,” Obama told Savannah Guthrie of “The Today Show.”

Obama’s answer marks a change in tune after telling “Today’s” Matt Lauer six months ago that he could never imagine the New York businessman delivering a State of the Union address. “I’m pretty confident that the overwhelming majority of Americans are looking for the kind of politics that does feed our hopes and not our fears,” Obama said at the time.

When asked during his interview with Gutherie if he was “worried” about Trump and the current election cycle, Obama responded by saying, “I’ve seen all kinds of crazy stuff happen.”

Obama’s remarks come after former Secretary of State Hillary Clinton clinched the Democratic Party’s nomination Tuesday evening at the organization's convention in Philadelphia, becoming the first woman ever nominated as a major party’s presidential candidate.

Recent polls have shown Trump beginning to take a slight lead over Clinton ahead of the November election. A Reuters/Ipsos poll released Tuesday gave Trump a two-point lead over Clinton with 39 percent of likely voters saying they would support the author of "The Art of the Deal." The poll was conducted between July 22 and 26 and surveyed 926 likely voters. The poll had a 4 percentage point margin of error meaning that the candidates are almost even in support four months out. 

In the interview released Wednesday, Obama said Trump was unlike past Republican presidential candidates who had detailed policy proposals and had studied up on world events having a grasp on basic knowledge like the differences between Shia and Sunni Muslims.

“He doesn’t seem to have any plans or policies or proposals or specific solutions,” Obama said. “The good news is we’ve got a candidate in Hillary Clinton who has put out very specific plans and programs and is telling you exactly what she’s going to do.”

Obama is scheduled to address the Democratic convention Wednesday evening. He is expected to speak about hope and remaining optimistic about the country’s future.
