Hey, I'm down here in Macon. Here's my $.02.
The last version looks a LOT like the real estate salespeople billboards I see frequently on I-75. At least the 'Flag' version looks like a political ad.
I agree with kylejack about the 'Protect our'...troops, economy, borders suggestion also. I like the happy picture, but I like the dark, moody, melancholy one for some reason too.
Don't say less war or less taxes, either. It's more correct to say fewer. Less Government is great, though.
Personally I loved what that guy did at the Philly rally with the Geico tagline. You know the one: "I just saved a bunch of money by switching to RON PAUL." Perfect.
