I don't think Tony Blankley overstates the situation at all in his column. Excerpt (bolding mine):
The other difference is that George W. Bush didn't lie about weapons
of mass destruction in Iraq. He was merely mistaken. Whereas President
Obama told a whopper last week when he claimed he was not for bigger
government. As he said Tuesday night: "As soon as I took office, I
asked this Congress to send me a recovery plan by President's Day that
would put people back to work and put money in their pockets. Not
because I believe in bigger government - I don't." . . .
If President Obama were to try to misrepresent his positions for the next four years, there would be nothing he could say that would approach the inaccuracy of his claim last week that he is not for big government. It is the essence of the man and his presidency. He doesn't like America the way it has been since its founding - and it will take an abusively big government to realize his dreams of converting America into something quite different. If you don't know that, you don't yet know Barack Obama.
