A couple of thoughts some pundits are offering after (the other) Dr. Paul's victory over the Republican establishment's candidate in the Kentucky Primary:
1 - The establishment is in trouble and the activists are moving the party further to the right and forcing out the heretics. Paul may be too conservative for Dick Cheney.
2 - Paul's objections to civil rights, including questions about the wisdom of the Civil Rights Act of 1964, have introduced new questions into the upcoming elections. Do private businesses have a right to discriminate?
