Romney's people try to cut a deal first, but Ron Paul guys apparently didn't trust them. They also figured that joining Huck improves their chances for a brokered convention. After all, in 1860 Lincoln barely made it into the brokered convention with only 22 delegates (out of 233).
What a crock! And you can't back it up because now Paul has given up any notion of being independent of the other campaigns. He made a deal for the only reason that naturally comes to mind - that he actually would get some delegates. Doesn't sound like the act of a man with strong convictions about the nefarious doings of Washington.
