Tomorrow (January 31) is the last day to join Democrats Abroad and participate in the Global Primary on February 5. You may also show up on the 5th at your voting location and join then, but if you want to vote by mail or online, you must register as a member by the 31st.
To join, go here.
For information about the Global Primary on February 5, go here.
Interestingly, the first country to vote (longitudinally) will be Indonesia, where Barack Obama lived for several years as a child.
