Evidence, please.
The large grass-roots movement that surrounded his campaign isn't enough? The "Ron Paul Revolution" had alot of people excited about politics and while not formally called the "Tea Party Movement" at that time it did contribute significantly to the explosive rise of grassroots movements in American Politics.
Since his "Campaign for Liberty" got going Paul has started to distance himself from the mainstream teapartiers but has maintained his beliefs and positions. He continues to be a Republican in name but is far more Libertarian in his views, which says something about how American Politics has changed in just 10 years and the large steps to the left that have occured even under Bush.
The man has to be given credit (along with a great many other people) for boosting the movement along and showing what ordinary citizens can do to change the tide in modern politics.
Look up the Liberty Caucus. It’s there. I’m on my BlackBerry and cannot do much research. Would you suppose that someone so dedicated to original intent WOULDN’T support and encourage the Tea Parties?
