Ed Florack has a brilliant essay at PJM, which goes a long way towards explaining what’s wrong with the Republican Party:

While conservatives and libertarians make up the majority of the GOP, they don’t make up even half of the leadership. The rank and file are interested in principles of conservatism and libertarianism. They want to see those principles applied to governing. The GOP leadership has no interest anymore in such matters, being more enamored with attaining and remaining in power. Those principles are just standing in their way.

And this (from William F. Buckley):

The profound crisis of our era is, in essence, the conflict between the Social Engineers, who seek to adjust mankind to conform with scientific utopias, and the disciples of Truth, who defend the organic moral order. We believe that truth is neither arrived at nor illuminated by monitoring election results, binding though these are for other purposes, but by other means, including a study of human experience. On this point we are, without reservations, on the conservative side.

Read it all.
It is interesting how much conservatives and libertarians happen to agree with each other on the problem with the GOP.
Now if they could just agree to disagree on the rest, some progress might be made towards something resembling unity. It never ceases to amaze me how much strife there is over social issues which aren’t within the federal purview anyway.
Were I in the so-called “GOP leadership,” I’d do everything in my power to keep these disagreements festering, and if they’ll never be solved by the federal government, so much the better!
