Ahead of the US election in November, the Democrats and Republicans are set to hold scores of primaries and caucuses to select their party's presidential nominee.

Among the most important of the upcoming dates in the US political diary is Super Tuesday, during which 17 caucuses or primaries will be held, with many seeing the day as a test of whether candidates can appeal broadly on national issues of importance, as opposed to tailoring their message in each state.

Currently in the running for the Democrat nomination are Hillary Clinton and Bernie Sanders, while competing for GOP nomination are Donald Trump, Marco Rubio, Ted Cruz, Jeb Bush, Ben Carson, Chris Christie, Carly Fiorina, John Kasich and Jim Gilmore.
