New Hampshire began voting on February 9 in the first US presidential primary with Republican Donald Trump calling on supporters to propel him to victory and Democrat Bernie Sanders primed to upstage Hillary Clinton.  The northeastern state, home to just 1.3 million people, sets the tone for the primaries and could shake out a crowded Republican field of candidates pitting Trump and arch-conservative Senator Ted Cruz against more establishment candidates led by Senator Marco Rubio.
