With Republican Donald Trump holding a commanding lead in polls of the state, Florida Sen. Marco Rubio and Texas Sen. Ted Cruz are competing to make a strong enough showing to gain a share of the state's delegates.

On the Democratic side, Hillary Clinton’s rout of Vermont Sen. Bernie Sanders on Saturday provides a good indicator of how Georgia voters will swing on Tuesday. Sanders campaign hopes to keep it closer than the nearly 50-point spread he lost in the state, though he’s spending the final hours before the vote rallying voters in the Northeast and Midwest.

Rubio will return to Atlanta Monday to make a final pitch to Peach State voters, just two days after he and Cruz held near-simultaneous events in the city. Yet he'll have to compete for attention with Trump, who will headline a rally at Valdosta State University on Monday night.
