Joe Biden is no longer sniffing women's hair on the campaign trail

Democratic hopeful Joe Biden is not burying his face in women's hair anymore, as was his wont, reports Politico:

But after nearly a week on the campaign trail, including nearly a half-dozen events in Pittsburgh, Iowa and South Carolina, it appears Biden got the message. Gone are the episodes of canoodling with voters, replaced by a less tactile brand of retail politicking marked by selfies and more physical reserve than Biden is accustomed to.

Where once Biden was famously photographed in an Ohio diner burying his face in the back of a woman biker's head, rubbing her shoulders and sitting so close that it initially appeared she was sitting on his lap, the former vice president is now showing signs of deliberately holding back in one-on-one encounters.
