AUGUSTA — To some at Georgia's Republican Convention, Donald Trump was simply the "Republican presidential nominee" or the man at the "top of the ticket," his name going notably unmentioned in both fiery speeches and quiet conversations.

To others, his name was enthusiastically invoked as the bulwark against another four years of Democratic control of the White House, an unstoppable political force who can upend the Washington status quo.

Two distinct blocs of Republicans dominated the two-day conclave in Augusta, and they reached a hesitant truce amid repeated calls of unity from party leaders and the grass-roots activists who make up the backbone of the GOP movement.
