POLL: If another 9/11 happened today would Americans reunite despite the political divide?

Two decades later, America seems more polarized and divided then ever with many questioning whether this disunity can ever be reconciled.

If there was another 9/11 today, would Americans be able to put their political differences aside and reunite as a nation?
