The carbon free voting campaign that started in California:

should be taken nationwide
Look here to learn how to vote by mail in your state:

In some states, voting by mail is called absentee voting and some
have
no-excuse absentee voting that premits every voter to vote by mail.
For example, in my state, NC, no-excuse absentee voting is allowed
and
you can arrange to have a absentee ballot sent to certain close
relatives and in-laws.
Spread the word. You will be surprised how many pro-environment
voters
you will find that don't know that voting by mail is even permitted
in
their state.
