Citizens who have registered to vote absentee can start to vote “in person” absentee in Missouri.

There aren’t a lot of Missouri absentee ballots cast–they are an “excuse required” state according to NCSL and according to our figures, 6.2% voted absentee in 2010 and 11% voted absentee in 2008.  We have not collected data on absentee voting in the primary (and can’t find it on Missouri’s website).
