Leno is the asshat who, during the campaign, said he didn’t make jokes about Obama because there was nothing about Obama that lent itself to joking.
I think that was Letterman.
Either way, I did not enjoy the Bush interview. Leno showed footage of a couple of Bush gaffes, like trying to open the locked doors at an overseas conference. Bush had a good retort, but it is as plain as the sun in the sky that the same treatment would not be afforded Obama, or Bill Clinton for that matter. Those two are a treasure trove of stupidity and lies, but you would never know it.
The bias is so ingrained, that nobody even knows it's happening right before their eyes.
One other thing is when Leno got Bush to admit that the “Mission Accomplished’ banner was a mistake. I have defended the use of the banner because it was meant to show that the Carrier and its crew accomplished their mission. President Bush gave the Left verification of their lying propaganda.
