Republican candidates are looking towards crucial primary in Indiana on Tuesday, where Trump is leading by a whopping 15 points

Virginia has 13 at-large delegates, 33 congressional delegates, and three slots held by party members for total of 49

Delegates are still bound by primary results, but loyalties to Cruz could prove useful should there be a contested national convention

Trump won the Virginia primary with 34.7per cent of the vote and 17 delegates compared the Cruz's eight on March 1

Ted Cruz has taken 10 of the 13 at-large delegates in Virginia, even though he came a distant third place in the state's Super Tuesday primary, where Trump won with 34.7per cent of the vote.

The victory will only play a role if Trump fails to secure the GOP nomination in the first round of voting at the national convention and the state's delegates, many of whom personally lean towards Cruz, are given free reign.

Virginia's delegates are still bound by the March 1 primary results, where Trump secured 17, Marco Rubio came in a narrow second with 16, and Cruz was awarded eight with just 16.9per cent of the vote.

Cruz is now looking for one crucial chance to block Trump in Indiana, a winner-takes-all state with 57 delegates, on Tuesday.

But the Texas senator will really have to pull one out of the hat as polls currently show him trailing the Donald by 15 points.

About 2,500 people attended the state's Republican convention at James Madison University in Harrisonburg on Saturday.

In addition to the 13 delegates selected on Saturday, Virginia's 11 congressional districts have yet to elect three delegates each, adding another 33 delegates. Three more delegate slots will be filled by party leaders for a grand total of 49.

While Virginia's slate of delegates may prove to be a moot point if Trump can avoid a contested nomination, his supporters cried foul, saying the 10-3 ratio ignored the 'voice of the people'.

Elected delegate Kathy Byron, who pledged her support for Cruz should it come to a second national convention vote, told The News & Advance: 'We're not talking fair.

'We're just talking rules right now...I don’t know about fairness, how fairness is going to come into play. Right now we’re just following the rules.'

Trump has already called himself the 'presumptive nominee' and celebrated his string of six victories by declaring he had broken the four-figure mark on his way to the holy grail of 1,237 needed to win the GOP nomination.

But Cruz's establishment roots were evident in Virginia, where the majority of the convention-goers agreed to a 10-3 split.

Members of the Cruz camp suggested they could have gone for a full shut-out on Saturday, with former Virginia Attorney General Ken Cuccinelli saying: 'This was an olive branch. If we wanted a 13-zero slate we could have had one.'

'It's a screw-you branch,' Corey Stewart, chairman of the Trump campaign in Virgina, retorted.

But he remained confident and said, 'The campaign is convinced that we're going to hit 1,237, so this is a moot issue. There will be no second ballot,' Politico reported.

Trump leads the Republican race with 997 delegates ahead of Cruz's 566 and Kasich's 153.

During the March 1 primary, Trump won 17 bound delegates in Virginia, Rubio nabbed 16, compared to eight for Cruz, five for Kasich and three for Ben Carson.

Delegates in Virginia are still bound to candidates who have dropped out during the first round of the national convention, although they usually become 'unbound' for most states.

The Republican candidates are looking ahead to a decisive primary in Indiana on Tuesday, with Trump hoping to lock down the nomination while Cruz is crossing his fingers for an upset.

Trump has the support of 49per cent of Republican voters in Indiana compared to Cruz's 34per cent, according to a poll reported by NBC. John Kasich holds 13per cent.

The Donald, who has staked his position in the race by emphasizing his status as a political outsider, has decried the voting system that has jilted him of delegates in states where similar results played out.

The businessman won 58 delegates in the March 22 primary in Arizona with 47.1per cent over Cruz's 24.9, but secured only two of 28 at-large delegates should there be a contested national convention.

Voters at the state convention were told to log onto websites presenting a selection of slates, but former Arizona Governor Jan Brewer's name was left off the Trump ballot.

He said: 'The people of Arizona got cheated, I got cheated, and the Trump delegates got cheated.'

After Trump lost all 34 of Colorado's delegates to Cruz given the state's complex voting system, he said: 'The system is rigged. It's crooked.

'This was a political hack deal, like so much of our country. This is what our country's all about I guess.'

Unlike primaries in most states where voters directly choose between the candidates, Colorado's voting system for Republicans involves several rounds.

On March 1, or Super Tuesday, voters attended caucuses in their precinct to select delegates to attend county-level conventions. Those delegates went through yet another round in seven congressional districts in the state.

Each of the seven district conventions then chose three delegates to go on to the national convention for a total of 21 pledged to Cruz on Friday.

On Saturday, an additional 13 delegates, all of whom went to Cruz, were selected from a pool of more than 600.
