The way I see it, the Republican brand can be broken down into five "flavors" (if you will).  Arranged alphabetically, they are: "Conservative Republican," "Liberal Republican," "Libertarian Republican," "Moderate Republican," and "Tea Party Republican."

I'd easily burn through more pages and words than the combined length of America's Charters of Freedom defining those five categories, and I'll wager that I'd still blow it on at least one point of careful delineation.  I've learned that it's much easier to define the categories through easily-identifiable example pairs.  Thus, the categories break down as follows:

• Conservative Republican (Reagan & Agema)
  
• Liberal Republican (Romney & Milliken)
  
• Libertarian Republican (Paul & Amash)
  
• Moderate Republican (Ford & Engler)
  
• Tea Party Republican (Palin & Colbeck)
