Hell no! Why on earth should Perry drop out? Or anyone else for that matter. Do they not have a constitutional right to seek public office?
Perry, Romney and Huntsman are the only ones still in the race with executive experience and Perry is the only one of those two who can point with pride to his record of accomplishments and patriotism.
Don't worry; no-one's being forced to drop out. What you read are recommendations and suggestions, however partial.
