Good on you, and I'm not just saying that because Ron Paul sucks.
Thank you for the compliment, even though it was a bit 'left-handed'. i came to the conclusion long ago whilst watching with disgust the tactics of Democrats registering as Republicans during primary season in order to have nominated the person they percieved to be the weakest (or most vulnerable) Republican candidate for a particular office.
If it was wrong for the Democrats, it is wrong for Libertarians such as myself, who are NOT Republicans.
Contrary to your last assertion however, Ron Paul decidedly does not "suck". What DOES suck is that people actually believe that there is a discernable difference between the two major political parties, in spite of decades of disillusionment and disgust from the hands of candidates/nominees/electees of both major parties.
