Paul embraced the corrupt Republican Party because the corrupt two party system has a monopoly on the system making a 3rd party almost impossible.
Yes Paul uses the Republican party infrastructure for his own means. Since then he has resigned from Congress due to his disapproval of Reagan.
He has said that Bush should be impeached over the North American Union and the Amero, which do not even exist.
He has gone before Congress and accused Republicans of contriving a Gulf of Tonkin incident in order to provoke a war with Iran, which didn't happen.
His followers have called Republicans Rino's, Zionist war-mongers, war-criminals and so forth, and all the while insisting that they are the true Republicans. You called Republicans corrupt about 5 times in your post. If that is the case maybe you owe it to yourself to make other arrangements. Goldwater was a long time ago.
