I may not be American - but I have done extensive research of his speeches across Youtube and undoubtedly - he is fighting for what is right for America and this would eventually lead to a positive impact on the rest of the world.
For one , Ron Paul of a right idea on governance. The state , the laws , the government itself ought not to be intervening into the personal habits and the liberty of the people.
America was known as the land of liberty. Where the people's lives were not affected by federal laws which contradicts this "freedom" in question.
A government exists to protect and guide the people - but not control them as they see fit.
Plenty of money was squandered on pointless wars as well.
America has intervened in many wars which does not affect them in an adverse way - trying to police the affairs of others across the globe and building up bases across countries and nations - this in turn causes the country to squander a large amount of money and in turn , America have to loan money from foreign countries to sustain an empire which they CAN NOT afford to maintain in the first place.
He had also made a fine point on the terrorist attacks - America was not attacked because it was free and prosperous - it was attacked because of American influence within THEIR country.
Foreign military influence on one's homeland would be one of the worst things that could happen to a country so it is of little wonder to think that there would be people fighting back for their homes and beliefs.
He had also mentioned the various reasons for the country's economical decline and in many ways , his honesty and quick thinking really makes him a suitable candidate to be the President of America.
