As Oliver puts it, American politics is a "circus of crazy" that is unmatched in the world.
The former Comedy Central star was promoting his upcoming HBO series at a Television Critics Association meeting Thursday.
Oliver honed in on one particular politician, former Alaska Gov. Sarah Palin, after learning she was to host a Sportsman Channel breakfast for the TV group. Palin was recently announced as the host of a new channel series, "Amazing America with Sarah Palin."
A smiling Oliver predicted that the onetime GOP vice presidential candidate would do to sports what she did for politics. He didn't elaborate.
