Trump, Haley face off in Washington Republican primary

WASHINGTON - Presidential contenders Donald Trump and Nikki Haley will face off in the Washington Republican primary on March 3, a small-stakes contest that could be one of Mrs Haley's best shots to score a win over the former president.

The United States' capital city sends only 19 out of 2,429 delegates to the Republican National Convention in July, where the nominee is formally selected.

The results from March 3 are unlikely to change the trajectory of a race that Trump appears to have stitched up, having won all the previous nominating contests.

Still, the District of Columbia could be unusually fertile territory for Mrs Haley, said a high-ranking official at SFA Fund, the main super PAC (political action committee) supporting her bid.

During the last competitive Republican nominating contest in the District of Columbia in 2016, Trump received less than 14 per cent of the vote and no delegates, even as he went on to win the nomination nationally.

The local party's single polling station in a downtown hotel has been open during daytime hours since the morning of March 1, and it will close for the last time on Sunday at 7pm local time (8am on March 4, Singapore time), after which votes will be counted.

The city is 100 per cent urban, and a relatively high proportion of residents hold a degree. The core of Trump's base skews rural, and he is particularly strong in areas with low educational attainment.

If Trump wins, it would illustrate how he maintains a core group of supporters within every demographic and geographic slice of the Republican Party.

A lack of local opinion polls and the extremely limited number of Republicans in the city has created a degree of uncertainty about the primary's outcome.

Mrs Haley campaigned in the District of Columbia on March 1, hosting an event in the same hotel where the polling station is located. Trump's campaign has been largely absent in the city, beyond sending out texts to local supporters asking them to vote.

The Democratic primary in Washington will be held in June.

On March 5, voters in 15 states and one US territory will caucus or go to the polls on the biggest day of nominating contests in the presidential primary. Known as Super Tuesday, 874 Republican delegates will be up for grabs. REUTERS
