Oh there's no question about the importance of WFB to modern conservatism, and it's no small point that he would concede that Reagan could beat him on occasion. But he was focused on the fight against communism.
But after communism fell in Europe and Russia, he went wobbly.
Yes, he was specifically against Communism, but when he was on the Firing line Program he was always against the liberals on everything. He was always a Gentleman even when in conflict with a less than Gentlemanly Democrat or opponent. That lack of mean spiritedness and ability to debate with decency set the standard for the Conservatives. It is not something that can be duplicated today because of the viciousness of those out of power. Scratching,clawing,insulting,interrupting are how Democrats handle Debate. All the Pubbie has to do is clear his throat or take a breath and the nasty Dem will attack like a mongoose.
