How did suffragists efforts at the state level affect their effort to win the right to vote at the national level ?

This is how the suffragists' efforts at the state level affected their effort to win the right to vote at the national level:
Towns, counties, states and territories granted suffrage, in full or in part, throughout the 19th and early 20th century. As women received the right to vote, they began running for, and being elected to, public office. This opened up the idea to a more national effort to win women the right to vote/get the 19th Amendment.
