What senator Dole's comment is about is primary politics--and one man's opinion, albeit a man of some stature, regarding the prospective outcome of the GOP presidential race. But, his comments also represents the opinion of others who may not share the senator's particular brand of politics, but agree with him on this.
Primary politics can get so messy, you know what I mean? Everyone's got these pesky different opinions, you gotta spend time thinking about things other than food and sex. I hate hate primary season.
