Well, the Daily Paul folks consider Matt Bevin to be one of their own: http://www.dailypaul.com/299381/please-vet-matt-bevin-matt-bevin-to-primary-mitch-mcconnell-in-2014
Bevin claims that his foreign-policy views are similar to those of Ron Paul: http://www.ronpaulforums.com/showthread.php?422465-Kentucky-Kate-Is-Matt-Bevin-the-Real-Deal
Bevin can’t get full-throttle Paulbot support, though (unlike Thomas Massie in the 2012 KY-04 race), because Paulistinian scion Rand Paul endorsed Mitch McConnell for reelection last year as a way of paving the ground for his own reelection and/or a presidential run.
So you evidence to assert Bevin is a ‘paultard’ is that he is viewed positively by an online forum... and he stated he has non-interventionist foreign policy views.
Conclusive.
