The original group of 16 is now down to 12 with this morning's announcement.
Monday morning, US Senator Lindsey Graham announced he was quitting the race for the Republican nomination for President of the United States.
Senator Graham's campaign never achieved strong traction and was mired low in the polls. This is despite the fact that he has been a strong, respected Senator from South Carolina which is a key initial primary state.
Much of the reason may be the extremely crowded Republican field, which initially numbered 16 contenders. Lindsey Graham joins Rick Perry, Bobby Jindal, and Scott Walker who have already left the field.
Lindsey Graham was strong on national defense, but Donald Trump and others of the Republican contenders have also taken strong positions on defense. As a result, he found it hard to break out and establish a strong, unique position.
Who will be next to drop out? The field is now down to 12.
