Primary elections are funny creatures. They can take on many different meanings. For candidates who win the primary, they point to the results and declare themselves on a roll and deserving of support. Politicos study the results much like they do polling data. This helps them determine who should be considered for general election support both financially and otherwise.
The Primary is often referred to as a “beauty contest” because it most often doesn’t determine who is the ultimate winner, unless the district dynamics are such that the primary victor has no real opposition in the general.
