The Obama girl thing cheapens a campaign for the The President of the United States of America to me. Part of why I like RP is that, his uncorrpupted, principled, down to earth image can restore respect for America, and the Oval office.
I see the other side to it and if it must be done, may I make some suggestions.
Do it with class, and RAISE THE BAR.
Get Ron Paul 6 Spokesmodels "not girls".
Choose an african american, an asian, a latino, an indian, and two whites one a little girl next door country and one a little hip city.
Center the African Anmercian girl around some cool jazz/blues image, the asian around some tranquil Zen music, the latino around some spicy salsa, the indian around indie rock, and the two whites around some rock and pop.
Give them each their own Videos. I can elaborate more on the imaging of each if this idea appeals and someone wants to run with it.
The idea is, to get the public voting and warring over for who is the BEST RON PAUL spokes model, and steal the thunder away from the other candidates girls.
See what I am seeing here?
