Who do you think were the ugliest First Lady's of the United States?

There are so many hot Royal wives and daughters so I was just looking up First Lady's of the US to see if there were any hotties. I was sadly disappointed.

The Ugly List:

1) Michelle Obama

2) Elenor Roosevelt

3) Hillary Clinton

4) Mary Todd Lincoln

5) Martha Washington
