If we’re only counting general elections, then yes. If primaries count, then I’ve voted for Obama a total of five times, and for Sanders four times.
Am I missing something obvious in the math, or did you vote in multiple presidential primaries of the same cycle &/or somehow vote for Obama in the 2004 IL Senate election & then Bernie in at least 2 of his VT Senate elections?
The 2016 WA primary and caucus format would explain why he may have made 3 Bernie votes. Not 4 though unless he wrote in Bernie in the general though.
