It's a tax. Roberts correctly identified it as a tax.
If you don't like the tax, take Roberts' advice and get rid of the executive and legislators that voted for the tax.
It's a tax, only if you also believe that paying a fine for a speeding ticket is also a "tax", or paying a fine for violating ANY law is a "tax".
It's pretty simple logic, junior.
Roberts voted the way he did because he wants the American people to "experience" what massive left wing economic destruction is all about, with the end result being the destruction of the Democrat party for many, many years to come.
"We The People" have had enough of leftist political ideology and shortsighted and nonsensical leftist legislative nightmares. Roberts wants to make sure those "on the fence" FINALLY "get it".
The joke is on YOU, leftist lemmings.
Enjoy your Obamacare.
