US election; Trump wins in Mississippi, Michigan and Hawaii

Donald Trump has won three more states,
Michigan, Mississippi and Hawaii, in his bid to be
the Republican White House nomination.
In the Democratic race, Bernie Sanders had a
surprise victory in Michigan, but Hillary Clinton
increased her overall lead with a big Mississippi
win.
Ted Cruz won a Republican-only race in Idaho.
The states are the latest to choose candidates to
compete in November's presidential election.
It was a terrible night for Republican Florida
Senator Marco Rubio, who came in a distant fourth
in both Michigan and Mississippi, a week before his
must-win contest in his home state.
Mr Trump, a businessman with no experience of
elected office, leads the polls in Florida, from where
he delivered his victory speech on Tuesday night.
"One of the things I am most happy about is the
turnout has been just massive… I think it's the
single biggest story in politics today," he said at a
press conference in Jupiter.
With his victories, Donald Trump has solidified his
position as the Republican front-runner,
withstanding a barrage of negative advertisements
questioning everything from his business acumen to
his use of vulgar and profane language.
Rather than deliver a conventional victory speech,
the billionaire held a news conference and conducted
what looked in parts like an infomercial, arguing
that products that bear his name, like bottled water
and wine, are commercial successes.
But it's the Trump political brand that's not only
proving highly popular but also resilient to attacks
from establishment Republicans who have intensified
their attacks in the hope of slowing his momentum.
Showing how the normal political rules do not
apply, Trump reckoned that one of the attack ads,
bleeping out various swear words he's uttered during
the campaign, actually boosted him because it
showed that he's not bound by political correctness
and tells it like it is.
He also said he would be more presidential than
anybody except Abraham Lincoln and that "no one
is more conservative than me".
The Democratic opponent Mr Trump is most likely
to face if he gets the Republican nomination, former
US Secretary of State Hillary Clinton, addressed
voters in Ohio after her Mississippi win.
"Running for president shouldn't be about delivering
insults," said Mrs Clinton, in a thinly veiled dig at
the outspoken Mr Trump.
"It should be about delivering results."
Mr Sanders' win in Michigan came as a shock after
weeks of polling that suggested Mrs Clinton was
well ahead.
"I am grateful to the people of Michigan for defying
the pundits and pollsters and giving us their
support," Mr Sanders said in a statement following
his win.
"This is a critically important night. We came from
30 points down in Michigan and we're seeing the
same kind of come-from-behind momentum all
across America."
Analysts say conservative firebrand Mr Cruz appears
to be the only candidate capable of stopping Mr
Trump, who has been fiercely criticised by the
Republican establishment.
The party's 2012 nominee, Mitt Romney, described
Mr Trump as a bully and a fraud who would lose a
general election because of his extreme positions on
immigration and Islamic State.
A central plank of Mr Trump's campaign is to
deport 11m undocumented migrants and build a
wall on the southern border, paid for by Mexico.
The primary and caucus elections determine the
number of delegates assigned to each of the
candidates.
The delegates then endorse their candidate at the
party conventions in July. To secure their party's
nomination, a candidate must win a majority of
delegates.
