First US Republican debate concludes

Republican Party also is referred to as GOP - Grand Old Party. It is one of the two major parties in the US, the other being the Democratic Party.

It was founded by anti-slavery activists and Whig party members in 1854.

The party's philosophy is based on American conservatism generally supporting free market capitalism, strong national defence, opposing regulation and labor unions etc.

The Republican/Democratic party debates are a part of nomination campaign to secure a party nomination.

They are meant to win the support of 'delegates' who have the power to select a party's presidential nominee (voters do not directly select presidential nominees).

Delegates are people who represent a national political party at the party's national convention.

Each political party uses their own nomination process.

Republican Presidential debates occur among candidates for the Republican Party's presidential nomination in the national election.

The Republican National Committee announced that there would be 12 debates in the 2015–2016 debate schedule.

Fox will look at the five most recently conducted national polls from "major, nationally recognized organizations that use standard methodological techniques" to decide the top 10.

The rest of the candidates will take part in the 5 pm debate.
