After Donald Trump’s decisive victory in Nevada, Texas Sen. Ted Cruz and Florida Sen. Marco Rubio are still locked in a bitter battle for second place.
Their fight has only intensified after Iowa, where Cruz won while Rubio surged to a surprising third-place finish. Cruz bested Rubio in New Hampshire, but they flipped places again in South Carolina where Rubio eked out second place over Cruz by just 0.2%.
Rubio maintained his lead over Cruz in Nevada Tuesday night, but the two are desperately trying to wound each other and their other rivals before they turn to topple Trump.
Watch the video above for a primer on what is really going on in the battle between the two young Senators.
