It is my well considered opinion based on my knowledge of American History.
When you objectively compare the accomplishments of the men who are on our currency, the potential women candidates simply do not measure up.
The US simply has very few women who performed significant roles in US history. Here is a suggestion someone made just the other day.
Impressive, but still not good enough to get on the currency in my opinion.
Although I wouldn’t mind having Thatcher on our money.
I wouldn't either if she were an American and represented that same level of Statecraft that Margaret Thatcher accomplished in England.
