Voters will go to the polls until 8 p.m. tonight as the country’s heated presidential race comes to Louisiana.

The presidential primary comes after Super Tuesday voting during which Republican Donald Trump and Democrat Hillary Clinton both solidified their positions. Here’s a look at what to expect in the Louisiana primary:

WHAT HAPPENS ON SATURDAY?

The polls will open at 7 a.m. and close at 8 p.m.

Unlike other statewide races, the presidential primaries are closed races, meaning that only registered Democrats and Republicans can vote in their respective party’s races.

There are 1.3 million registered Democrats and a little more than 800,000 registered Republicans. There are also local elections in certain parishes but Congressional primaries won’t be held until November.

On the Republican side, 46 delegates are up for grabs while Democrats have 51 delegates. The delegates in both parties will be awarded proportionally to candidates who meet a certain threshold.
