"So far he appears to be not as good as his father, but still shows lots of promise and is poised to be the best person in the Senate. So far he appears to not be as libertarian as Ron Paul, but is still demonstrating that he has some good solid leanings in that direction for as little time as he has been in the spotlight."
Libertarians could be wrong about him; he could actually be more radical than his father, or he could fail to demonstrate the promise he has shown so far. His vote against renewing the USAPATRIOT Act and his proposed $500 billion budget cuts that included the entire Iraq War and the entire Afghanistan War are not anything that libertarians would complain about.
So why then does there appear to be a more extreme reaction to Randall Paul among the liberal punditry? Even Rational Wiki expresses greater skepticism towards Randall Paul than to Ron Paul as evidenced by the tone of their articles.
Part of it could be that Randall Paul has a stronger Tea Party affiliation. While the Tea Party movement was started by Ron Paul, he is no longer a part of it while Randall Paul was elected as a part of that movement. That would give liberals two criticisms against him, libertarianism AND the Tea Party.
But that is not sufficient to explain the hysteria over Randall Paul. The reason they are so hysterical is because he really is a greater threat.
Even though Ron Paul's ideas are rapidly becoming mainstream, he still suffers from the stigma of being considered a kook for so many years by those who tell the public what to think. Randall Paul is too new to have been stigmatized. Moreover, since the Republicans are trying to absorb the Tea Party movement, the Republicans cannot criticize the star candidate of that movement. Since Republicans have to be silent, lest they lose on their effort with regards to the Tea Party, that leaves Democrats to have to bear the entire burden of telling everyone how they should feel about Randall Paul.
Ron Paul is also near the end of his political career. If he does run for president, his age would be a great liability. Randall Paul does not have that problem. He is not only a lot younger, he has already achieved much higher office than his father did. Even if he is more moderate than his father, he's in a position to achieve much more, and to go even father than he has already gone.
Democrats have to do this on their own without Republican help. The ideas of the Pauls are more mainstream than ever. Randall is a Senator poised to go much farther and do much more. Even though he might be more moderate than his father, he is poised to do far more for liberty than his father did. No wonder the left is hysterical.
