Video: Cato Institute on Obama's State of the Union Address

Cato experts straighten out many of the twisted political statements made by US President Obama at last night's State of the Union address.

To quote George Orwell on "BlackWhite" (bold emphasis mine)

this word has two mutually contradictory meanings. Applied to an opponent, it means the habit of impudently claiming that black is white, in contradiction of the plain facts. Applied to a Party member, it means a loyal willingness to say that black is white when Party discipline demands this. But it means also the ability to believe that black is white, and more, to know that black is white, and to forget that one has ever believed the contrary. This demands a continuous alteration of the past, made possible by the system of thought which really embraces all the rest, and which is known in Newspeak as doublethink.

As exposed above politicians are very good at propagating doublethink.
