At this point if Carson doesn’t exit the race. It’ll be obvious that he relishes his roll as the spoiler.
Tonight in nearly ever state Carson won 5-10% of the vote. Most of which would go to Cruz...with or without a Carson endorsement.
If Carson dropped Cruz still would have lost New Hampshire, South Carolina, Nevada, Alabama, Georgia, Massachusetts, Minnesota, Tennessee, Vermont, and Virginia.
And that’s assuming every single one of Carson’s supporters would back Cruz.
