CNN's Erick Erickson on Libya:

Using the same rationale George W. Bush used to go into Iraq, Barack Obama has now gone into Libya.

Erick Erickson, just four sentences later:

Whether you think he lied, was misled, or was right, George W. Bush did make a case to Congress and the American people prior to going into Iraq that Iraq was training Al Qaeda and, given its weapons of mass destruction and ties to Al Qaeda, was an imminent threat to the United States.

Maybe I just missed it, but I don't remember Barack Obama claiming that Libya's weapons of mass destruction constitute an imminent threat to the U.S. I haven't seen any members of his administration warning of a “smoking gun in the form of a mushroom cloud.” The administration and its allies haven't been suggesting that Libya was behind the September 11, 2001 attacks.

So, no, Barack Obama isn't “using the same rationale George W. Bush used to go into Iraq.” Erick Erickson is just lying. And he's doing it incompetently -- he can't even make it three paragraphs without accidentally debunking his own nonsense.
