For the aspiring young assassin, a popular online games site offers kids the opportunity to assume the identity of a leading presidential contender and then shoot their political opponents in a series of armed confrontations in the White House. While the ammo is paintball, the game on the highly trafficked miniclip.com site allows kids to train a rifle scope on six presidential aspirants and squeeze off a hail of shots (which are accompanied with a rat-a-tat sound). The game, "Presidential Paintball," features six candidates in the crosshairs: Barack Obama; Hillary Clinton; John Edwards; Mitt Romney; John McCain; and Rudy Giuliani (it seems the game was developed before the ascension of Mike Huckabee). If a candidate wins a head-to-head confrontation, he/she advances to a new shootout, which occurs in various White House settings, including outside the Oval Office.
