This year's Super Tuesday in the United States has been the least disputed in history, paving the way for Donald Trump and Joe Biden to secure the nomination.
Trump had a crushing victory over Nikki Haley, who withdrew from the electoral race without explicitly supporting Trump.
The challenge for Trump is to unite the Republican Party and win the backing of moderate Republicans and independent voters.
Biden dominated electorally despite the protest vote in some states over his support for Israel.
Biden's main concern now will be to manage the response of his own voters to the Gaza war, the migration crisis and inflation.
Although mathematically Super Tuesday does not guarantee the nomination to either of them, the remaining primaries are a mere formality.
Conclusion: The electoral race is decided unless an unforeseen event occurs. Both candidates have a long-standing record and are elderly - Biden is 81 years old and Trump will be 78 - which becomes a challenge to attract American voters.
