A head to head comparison of the Louisiana 2020 Primary gives us an idea of the break down of the voters.

Joe Biden received 49% (212,439) beating Donald Trump, who received 46% (295,812), and Bernie Sanders who received 5% (19,845).

Donald Trump won 41 out of the 64 counties in the state of Louisiana, and Joe Biden won 23 counties.

These 10 counties play an important role in these primary elections. Even if a candidate does not achieve a sizable majority in one of the larger counties (East Baton Rouge, Jefferson, Orleans), they can still take the lead by capturing very large minorities in several counties.
