Democratic presidential frontrunner Joe Biden refuses to keep his hands to himself. 

After promising to respect women's space and not touch them without their consent, the former vice president made many very uncomfortable again this week when he rubbed his face up against a little girl's while on the campaign trail. 

During a stop in Des Moines, Iowa, Biden pressed his nose up against one young girl wearing glasses while meeting with potential voters and their families.

“Now, what grade are you in?” Biden grossly asked the girl before pulling away.  

Biden also gave a young boy a kiss on the top of the head after hugging both the children.

The past few months have been catastrophic for Biden and his 2020 campaign. 

During a recent campaign stop in Iowa, a woman said an interaction with the former vice president made her "really uncomfortable" because he would not stop grabbing her hand. 

The woman, a teacher who wanted to ask Biden about collective bargaining, said Biden should have asked before holding onto her hand throughout their more than a minute long interaction.   

"I think that he means well but, you know, he grabbed my hands right away and that was really uncomfortable," she told the Examiner. "He was very close and, in my mind, I'm like, this is part of our problem: Not recognizing that you need to ask first, or can I shake your hand? Not just grab your hands and hang onto them. That bothers me."

The 2020 election is still a long ways out, but Biden's gaffes are severely harming his 2020 chances.   

Biden came under fire back in September for telling a crowd that “poor kids are just as bright and just as talented as white kids.”     

In June, Biden came under fire for praising segregationist Democratic senators and boasted about working with them during his time in the U.S. Senate.

Since he announced his 2020 run back in April, four women have come forward and accused the former vice president of inappropriately touching them and pulling them in close to rub noses.    

All of these comments have been made in the last few months.    

Imagine how many more gaffes and controversial statements Biden will make over the next year.
