Not really fair for his art to be critiqued by "critics" since these paintings weren't meant to be public. He didn't hang them in a gallery. They were private.
I assume this hacking was meant to be a dose of his own medicine. It was under Bush that the Patriot Act and Homeland Security all came to be.
All in all...the emails and paintings are a non-issue. If anything this helped George. He can be seen as a quiet man enjoying the golden years of his retirement.
One last thing....sharing paintings of yourself in the shower and bathtub with your family is weird. Just my opinion. Now that's it out there in the open.
