Dependent upon the state you are in and if the GOP is "Ron Paul Friendly." I live in MN and the gop here doesn't respect us a whole lot but we have plants and have been encouraged to not wear RP gear, However, if RP is the dominant force at the location break out the buttons. I've been toying with the idea of having one of our RP supporters wear a button to get the other supporters that haven't been identified to know who to talk to, that way we can get names at the site and get a good slate of delegates. Be wary of people misrepresenting Paul to become delegates for Romney/Gingrinch/Santorum. There was an article accusing RP supporters of this, and yet it isn't us that is doing it, it is the other campaigns. (easiest way is to start talking issues, especially the tie of foreign aid as a weapon. Otherwise just test peoples knowledge in a friendly manner. (Votes on resolutions could help identify people)
