FYI: Just in case anyone wasn't able to get their registration sent in time to vote in their state's primary, the democratic party has a global primary where you can vote in person or via mail/email ballot through Mar 8. There are 121 voting centers in 40 countries or download the ballot to mail/email.
Happy Super Tuesday!
ETA: I see someone already posted this last night... and I didn't even put the link double oops!
