This would not surprise me.
Bernie seeks any attention and news media coverage he can get = free press.
With Bloomberg pumping out billions, Bernie does not stand a chance unless he can come up with some antics, so he has dropped in the polls.
Currently, on Sunday, the polls indicated the following order of popularity with Bernie in #1 and Biden at #5.
Warren is bouncing like a ball as she dances on stage.
B - Bernie
B - Bloomberg
W - Warren
B - Butt
B - Biden
