I will say that he sounds much more legitimate than it appeared. He doesn't provide his evidence, though, and frankly, I don't put it past him or his former employers (0bama) to provide disinformation.
To say all these small government parties are plants or at least working with Russia is completely bogus.
This setup is not unlike the mantra that the Tea Party is made up of racists.
But these are not small government parties. A common theme with them is breaking up Europe and national socialism. They are very good at criticizing the problems, but usually their program comes down to Banks/Jews/Foreigners/Americans have all the money and rob us and when we get the power we are going to take this money away from them. For some reason National Socialism is called right wing by the press.
Russia supports them as they are harming Europe.
