Jill Biden loves her Joe.

That's evident in a video that was going viral on Friday afternoon. The video shows Jill Biden introducing her husband at a campaign event in New Hampshire. She’s looks down at her remarks and says, “I’ve seen Joe up close" while inadvertently holding her hands apart.

The crowd laughs. Jill, looking lovely in lavender, stops, realizing perhaps how personal that statement really is. She smiles and turns to Joe who is sitting behind her. The crowd cheers more.

“It’s in my remarks, really,” Jill says, looking back at Joe and seemingly blushing a bit.

She pauses and tries to calm the cheering, chuckling crowd. The camera pans to a wider shot, showing Joe, too, smiling and laughing. She carries on and Joe laughs.

“I’ve heard the urgency in his voice when he comes and talks about the people he’s met,” she says.

At that point, Joe laughs and shakes his head with a big grin on his face. Oh, love. It’s a splendid thing especially on the often stale campaign trail. It’s even better when there’s an unintended double entendre.

Jill and Joe Biden seem real, authentic and still very much in love in the clip. It’s reminiscent of Joe’s recent photograph with a female biker in Ohio sitting almost on his lap in a diner. The Bidens are great at unscripted, real deal politics.

The couple, who married in 1977 after the 1972 tragic death of Joe Biden’s first wife and daughter, are brilliant at pulling off these moments.

It also explains why the Bidens are so popular. After all, Joe Biden’s speech at the Democratic National Convention topped all speeches at that convention and the Republican National Convention in television ratings.

Biden’s speech, according to Nielsen, was watched by about 43.6 million people.

Politicians often make such double entendres inadvertently. In June, President Obama said in a speech during a fundraiser about Ellen DeGeneres and her push-up contest with Michelle Obama:

“I want to thank my friend who accepts a little bit of teasing about Michelle beating her in pushups — but I think she claims Michelle didn’t go all the way down. (Laughter, according to the official White House transcript.) That’s what I heard. I just want to set the record straight — Michelle outdoes me in pushups as well.”

Did Barack Obama really mean it that way? Jill Biden almost certainly did not. It’s the crowd reaction in both cases that matters. Like Obama at the fundraiser, the Bidens got in on the joke on Friday and laughed.

Would Mitt and Ann Romney have been that comfortable about such a thing? Not likely.

In January, Sen. John McCain (Ariz.) cracked a joke in Pensacola, Fla., at a stop for Romney about how many other dignitaries were also at the event. He cracked a well-worn joke that he often used during his 2008 White House run.

“I feel a bit like Zsa Zsa Gabor's fifth husband,” he said. “I know what I'm supposed to do, but I don't know how to make it interesting.”

According to various news articles, Romney looked nervous.

“I thought we only brought one actor and comedian here today,” Romney told McCain. “Gosh, that was quite a repartee there, senator. That was fabulous.”

As one YouTube commenter said on Friday about the Bidens: “How can you not like these two, compared to Romney with his 47% and Ann with her ‘you people’ attitude?” But, perhaps, the best comment was this one: “They both probably still text each other dirty [stuff] all day. Awesome.”
