Missouri will be the smallest of the available prizes Tuesday as voters in five states make their presidential choices in primary elections.
There will be 71 Democratic delegates and 52 Republican delegates at stake in Missouri. Greater amounts will be available in Florida, Illinois, North Carolina and Ohio.
Missouri's delegates are likely to be split among multiple candidates, though each party uses different rules for determining that. Here are some things to know about Missouri's presidential primaries:
Polls will be open from 6 a.m. to 7 p.m. Tuesday. All registered voters can participate in Missouri's presidential primaries. They will have to pick a ballot for one party — Democrat, Libertarian or Republican — but there is no party registration and no records of which party people choose.
The Republican ballot will feature 12 candidates, the Democratic ballot nine and the Libertarian ballot five.
Missouri has 84 delegates to the Democratic National Convention. Thirteen of those are superdelegates — party leaders or officials who can support whomever they choose. That leaves 71 delegates that could be apportioned based on the primary results. Forty-seven of those will be divvied out based on how well candidates do in each of Missouri's eight congressional districts, with anyone getting at least 15 percent of the vote qualifying to receive delegates. The remainder of the delegates will be divided proportionately among candidates based on their statewide vote, with 15 percent again the minimum threshold to get delegates. That means Hillary Clinton and Bernie Sanders are both likely to receive some of Missouri's delegates.
Missouri has 52 delegates to the Republican National Convention. The state Republican Party is awarding delegates only to candidates who are still actively campaigning — Ted Cruz, John Kasich, Jim Lynch, Marco Rubio and Donald Trump.
If anyone receives a majority of the votes cast for active candidates, he would get all 52 delegates.
If not, delegates would be awarded as follows: 12 for the candidate who gets the most votes statewide, and five for every congressional district a candidate wins.
That means one candidate could get all of Missouri's delegates if he wins every congressional district. Or the delegates could be split among candidates depending on who fares best in each of the state's eight districts.
Missouri has not received a great deal of personal attention from the presidential contenders until lately.
Trump's event Friday in St. Louis marked his first campaign appearance in the state. He was to rally Saturday in Kansas City. A scheduled Saturday appearance by Cruz in St. Louis County was his first trip to Missouri since speaking to an Eagle Forum conference in September. Cruz also was to campaign Saturday in Kansas City, Cape Girardeau and Springfield.
Rubio held a campaign rally in Joplin in December. But neither he nor Kasich planned to come to Missouri in the final days before the primary. That's because they are concentrating on their home states of Florida and Ohio — viewed as must-wins for each of them if they want to sustain their campaigns.
Clinton was to campaign Saturday in St. Louis, marking her fourth trip to the state. She also came to the St. Louis area in December and June and spoke in Kansas City in July at a National Council of La Raza conference. Sanders, who spoke at that same conference, last came to Missouri on Feb. 24 for a rally in downtown Kansas City. He was to hold an event Saturday evening in Springfield.
Missouri's presidential primary will be the first meaningful one since 2008. In that year, President Barack Obama narrowly edged out Clinton in the statewide vote, but they ended up splitting the available delegates. Republicans used a winner-take-all approach in 2008, meaning John McCain got all of Missouri's delegates even though he received just one-third of the total votes in a close contest against Mike Huckabee and Mitt Romney.
In 2012, Missouri's primaries lacked much significance. As the incumbent, Obama faced little Democratic competition. Republicans didn't use the primary — held in February that year — as the basis for awarding delegates.
That's because they would have been penalized by the national party for holding a vote too early in the campaign season. Instead, Republicans used later caucus meetings to allot their delegates.
