Rush can be great at times (for instance his writing after the Supremes abominable decision on CFR).
But, too often he blows his own horn and stoops to cheap tactics, because basically he is an insecure man. He makes nearly as many enemies as the followers he gains. I prefer my heroes slightly loftier.
But, you can have him. If he would mature, he would be a better man, and more useful to the conservative cause.
