What to expect in every state in vital Super Tuesday vote

The biggest day of the US election campaign so far takes place on Tuesday, when voters in more than a dozen states will choose who they want to run for president.

On Super Tuesday, which almost always falls on the first Tuesday in March, 15 states and one US territory hold presidential nominating contests for both the Democratic and Republican parties.

Of the primaries and caucuses held thus far, only one or two states have been on the same day.

Donald Trump is on the cusp of clinching the Republican nomination and is expected to make big wins on Super Tuesday that could push his only rival, Nikki Haley, into suspending her bid to become the party’s nominee.

US President Joe Biden is also close to becoming the presumptive nominee for the Democrats after Tuesday’s primaries, having won every contest so far with no substantial challenge. Despite this, Marianne Williamson and Dean Phillips remain in the Democratic race.

Republican primaries are taking place in Alabama, Arkansas, California, Colorado, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas, Vermont and Virginia. Two states, Alaska and Utah, are holding caucuses.

During the Super Tuesday contests, Democrats and Republicans vote on who they want to run for president. Once those votes are tallied, delegates are awarded for each state.

Candidates need a majority of delegate votes at their party’s convention in the summer to win the party’s presidential nomination.

More than a third of all the available delegates for both the Republican and Democratic nominations are at stake on Super Tuesday. On the Republican side, 854 of 2,429 delegates – more than 35 per cent – are up for grabs, while about 36 per cent, or 1,420 of a total 3,979 delegates, are in play for the Democrats.

Mr Trump has so far earnt 273 delegates, according to a tally by the Associated Press, and needs 942 more to hit his so-called “magic number” of 1,215 to win the nomination. Mr Biden currently has 206 delegates and needs 1,762 to hit his magic number of 1,968.

Several names will appear on the ballot, including those who have dropped out of the race. This is because candidates have a window to withdraw from the contest, and once that window closes the ballots are printed. If a candidate withdraws after the ballots are printed they remain on there.

Some states have an option for “uncommitted” or “no preference”, which means a person can exercise a “party vote” but are not committed to any of the candidates listed on the ballot. In the Democratic primary in Michigan last week, 100,000 voters cast a ballot for uncommitted in protest against Mr Biden’s support for Israel’s war in Gaza.
