What Nikki Haley Believes

Republican Nikki Haley, the ex-governor of South Carolina and former U.S. ambassador to the U.N., has confirmed her intention to run for the White House in a campaign video posted Tuesday morning.

The one-time member of the Donald Trump administration was expected to formally declare her candidacy during a "big announcement" to be made on Wednesday, February 15, at an event in Charleston, South Carolina.

Instead, Haley tweeted a video announcing her presidential ambitions along with the caption: "Get excited! Time for a new generation."

So, where does she stand on the key issues, and how likely is she to succeed?
