What do you think about Walgreen (WAG) as a short- or long-term investment?

-- Mike from Texas

James J. Cramer: In my opinion, this company is the best of breed in the drug retail business. With that in mind, it's no surprise to me that Walgreen has chosen UnitedHealth Group ( UNH), another industry leader, to partner with for the new Medicare health plan. (Note: Cramer owns UnitedHealth Group for his ActionAlertsPLUS charitable trust.)
