Bush isn't on any money, lol. Neither Bush is, no modern presidents are.
I feel George Washington and Abraham Lincoln, who were so important for our country, kind of got shafted being on such small denominations. I guess that way you see them the most.
I am fine with keeping the bills with who is already on them, but if they have to change, I don't know how showing a "women's movement" on money will work. I also don't think that should be on money, nor should any movement. I think it should be a person on the money, usually of Presidential caliber, or very big importance.
I am not demeaning Harriett Tubman and the good she did, along with others, but I don't think they should be on money. Maybe have the first female senator or or congressman, or maybe the first female of political importance.
