I freaking LOVE Rush but was shocked he didnt know Mars lacked an iron core and a meaningful magnetosphere and therefore also a signifigant atmosphere.
Rush usually scores high on a geek meter.
Shocking, wow.
On the rest of the Mars stuff he was right.
Rush like me is probably coming to the inescapable conclusion that REAL Conservatism is not coming back in our lifetimes.
The best we can hope for is some relatively Conservative brand of populism that can win elections....i.e. Trump.
For someone as committed to the cause as Rush that has to be a real downer.
