When I read the statement from Revelations 18 that says;
As she glorified herself and lived in luxury,
so give her a like measure of torment and mourning,
since in her heart she says,
‘I sit as a queen,
I am no widow,
and mourning I shall never see.’
For this reason, her plagues will come in a single day,
death and mourning and famine,

I could not help thinking that was said by a person. In Isaiah 49, which also covers this, it gives more details and confirms my thoughts. This is not only a symbol but also a particular person. Then I came across a prophecy by William Barnham.

“And I saw a woman, lying, vulgar as she was, and she dominated the country. And I predict that a WOMAN will either be president or come into great power of some sort in the United States before the total annihilation of the world. Keep that in mind, and I have said it. I saw a WOMAN stand in the United States like a great queen or something (Rev. 18:7b). A great WOMAN will rise up in the United States, well-dressed and beautiful, but cruel in heart. She will either guide or lead this nation to ruination.”

Watch for this. She is certainly beautiful and well-dressed. She is already infamous for her cruel heart. A woman dressed in purple. 
This woman does not have to be president, but just the effective leader of the country. 
Kamala Harris has now, for all intents and purposes, taken over from Biden. Nearly all dealings with heads of state are now completed by Harris. Her history is littered with acts of cruelty and dishonesty. The main reason she is so unpopular. If you look at Harris's images on Google, you will find she is nearly always dressed in purples, blues, or mauves. She certainly fits the profile like a hand in a glove.
