Microsoft Bing may be testing polls for the knowledge panels they display on the right panel. If you search for [joe biden], and scroll down the right side knowledge panel, you may see a friendly poll or test.
This was spotted by Shameem Adhikarath and I am not able to replicate it, so this might be new, here is the screenshot he posted on Twitter:
Are you about to replicate this?
I guess Bing wants to make some of its search results more interactive and entertaining?
