There was a line of cars to get into the parking lot of the St. Charles County Election Authority Thursday morning. Voters are showing up in droves to cast their ballots early. No excuse absentee voting opened Tuesday in Missouri.  There are two voting locations in St. Charles County and the Election Authority of St. Charles County estimates 25% of the voting population will cast ballots during the no excuse absentee period. Despite the line of no excuse absentee voters Thursday, many did not make the trip to witness the annual public test of the voting tabulators.  The St. Charles County Election Authority typically holds the public voting machine test on the second Thursday before an election. Two volunteers — a Republican and a Democrat — picked machines at random and signed off on their accuracy. It’s one step in a long process of ensuring a secure election.
