Washington (CNN) - Joe Biden's manner of celebrating the start of his second term may offer hints of where the vice president sees himself in four years.
The potential candidate for the 2016 Democratic presidential nomination gave nods to both early voting states this weekend – attending an inaugural ball thrown by Iowa Democrats on Sunday, and inviting New Hampshire's newly elected Democratic governor to his official swearing-in ceremony on Sunday.

At the Iowa event, Biden may have gotten a little ahead of himself, telling the crowd he was "proud to be president of the United States."
"But I'm prouder to be Barack ..." he continued, trailing off as laughter erupted in the room.
"I am proud," he corrected himself, speaking over the crowd, "to be vice president of the United States."
If he was testing the waters for a presidential bid, he found a sympathetic crowd from the state which kicks off the presidential selection process with their caucuses.
"Well, there goes that," Biden muttered, attempting to move on.
On Sunday, another early state Democrat came to pay respects to Biden's second term in office. New Hampshire Gov. Maggie Hassan, elected in November with 55% of the vote, attended the vice president's official swearing-in ceremony with her husband and daughter at the Naval Observatory in Northwest Washington.
If Biden were to run in 2016, polls show he'd be a popular candidate, though not as popular as Secretary of State Hillary Clinton, who's also speculated to be considering a run.
A CNN/ORC Poll taken December 17-18 showed 66% of Democrats could support Biden in a presidential bid, compared to 85% who said they could support Clinton.
A more CNN recent poll, released in the middle of last week, showed the vice president's approval rating standing at 59%, with 38% saying they disapprove of the job he is doing. Biden's approval rating is up five points from last month.
