John Boehner isn't the only politician guilty of public displays of affection

Few things go together during a campaign cycle quite like politicians and public displays of affection.

And we’re not just talking about Vice President Joe Biden.

Vice President Joe Biden’s talks to customers during a stop at Cruisers Diner, in Seaman, Ohio in 2012.

They all do it. They kiss their spouses. They kiss cute babies. They kiss complete strangers.

Each politician has a unique and sometimes strange style.

And on Tuesday, House Speaker John Boehner, R-Ohio, did it again to House Minority Leader Nancy Pelosi, D-California, on Tuesday during a ceremony at the Rose Garden to celebrate the “doc fix” bill.

Here it is, in all of its slow-motion glory.

It’s not the first time he’s puckered up to Pelosi.

But it’s probably never a good idea to kiss a lady while holding a large weapon.

One of the more questionable examples of PDA in recent memory came not from a politician, but a politician’s spouse.

In 2011, Rep. Michele Bachmann’s husband, Marcus, went all-in with this kiss to one of his wife’s supporters.

With the 2016 presidential race getting in gear with Sen. Ted Cruz’s 2016 announcement on Monday, one thing is certain: We’re going to be seeing a significant increase in political PDA.

Some classic moments:

New Jersey Gov. Chris Christie

It’s an impressive move from Christie, with the rarely seen double baby kiss while also holding the babies.

The GIF came in response to a New York Times Magazine illustration where Christie was kissing a terrified baby.

President Barack Obama

The upper lip/cheek move misses the mark.

Both eyes closed, mouths open and going for the cheek. Odd.

Probably the only time an awkward kiss would make an awkward PDA less awkward.

They prefer to stare into each other’s souls.

Back in 1969, it was apparently OK to give an open mouth kiss to the Deputy Director of Civil Defense, Georgiana H. Sheldon.
