The Soda Tax: Yay or Nay?

Obama tried to tax sodas as part of his health care reform package, but it got destroyed by lobbyists.  Now some states are debating putting a tax on soda.  Honestly, at 1 cent per ounce it's not going to break anyone's bank (an extra 12cents per can...go check your couch!), but it could bring in millions of dollars to help fund various healthy initiative programs.  I, for one, think this a great idea.  Some naysayers think this is a slippery slope, that we could start taxing bread and milk next.  But really, soda has absolutely NO nutritional value.  In the scheme of our daily nutritional needs, soda is a luxury...and not a particularly healthy one.  What do you think?
