>>> DON'T FORGET: Please make sure you put "Ron Paul 2012" or "Ron Paul for President" on your signs. This was a HUGE problem with our R[evol]ution campaign back in '07. People where like "Who's Ron Paul" and "Ron Paul Revolution--what is that"? Somewhere in the Youtube ocean there is an old newscast about that very issue.
Great point, but it also depends on the context. If it's a sign that'll be used on its own, no doubt, you're quite right. We can't assume everyone knows who Ron Paul is, even today. But if it's a sign that'll appear amidst a sea of other RP signs -- for example, in a rush-hour 'sign waving' -- you can get away without it, and use the extra space for longer messages.
