Are there any Ron Paul supporters who still don't realise how used they were?

Ron Paul is well known to be on very friendly terms with Romney. Throughout the nomination race, he turned up at debates and attacked whichever non-Romney candidate (invariably hated by the GOP establishment) happened to be surging at the time, largely leaving Romney himself alone. Romeny reciprocated this, never directing too much of his energy against Paul, allowing Paul to effectively split the anti-establishment vote, the far-right vote, and the anything-but-Romney vote.

Once the combined efforts of the Romney and Paul had taken out any candidates disliked by the GOP establishment and it starting being called for Romney, Paul immediately stopped acting like somebody who gave a shit, giving the lie to every claim that it wasn't just about becoming the nominee, or brokered conventions, or any of that. His actions were totally inconsistent with being a rebel or a revolutionary, and completely consistent with being a tool of Romney and the GOP establishment.
