Aww, how cute, he thinks people take him seriously.

(CNN) — Vice President Joe Biden further fanned the flames of speculation Tuesday over a possible 2016 presidential bid.

While he was leaving a Delaware polling booth, Biden was asked whether it was the last time he’d cast a ballot for himself.

“No, I don’t think so,” he replied, smiling.

The vice president voted with his wife, Jill, Tuesday morning shortly after 7 a.m. ET at Alexis I. DuPont High School in Greenville. Biden represented Delaware as a U.S. senator for 36 years before becoming President Barack Obama’s number two.

While waiting in line for about 11 minutes, Biden chatted and shook hands with those standing in line or passing through the polling station. The vice president then stepped into the middle booth of three, where the poll worker announced, “Now voting, Joe Biden.”
