He put it on display again in his most recent comments on Russia.
Victor Davis Hanson of NRO takes it apart today:
"We didn't have to wait long for the much anticipated morally-equivalent message from Barack Obama: “We’ve got to send a clear message to Russia and unify our allies. They can’t charge into other countries. Of course it helps if we are leading by example on that point.” Let me get this straight: getting a Senate and House majority to authorize a bipartisan joint war-resolution, going to the UN, assembling a coalition, having a national and world debate on the wisdom of such an operation from December 2001 to March 2003, and then attacking a genocidal dictator, and staying on to foster a constitutional democracy are apparently the same "charge" "example" as an autocracy suddenly invading its democratic neighbor during the Olympics, and staying on to annex some of its territory?"
And I have to agree--usually Obama keeps his liberalism under wraps. But bit by bit, it has begun to leak out--equating what America did with regard to Iraq to a lawless invasion, implying that some rural people believe in God and gun control only because they're "frustrated", etc. He very much holds the ideas of the left elite. We should expose this as much as we can.
