I'm not sure anyone is necessarily opposed to it. It just seems like a weird thing to come out of the blue and appear on Twitter at this stage of the campaign. Don't politicians issue policy handbooks anymore to inform citizens what to expect from them? Seems a bit haphazard to make random statements on a media platform that not everyone has access to. It's an odd communications strategy.
Actually, I though I heard from him awhile ago that he was opposed to going back to the moon. After all, we did that 50 years ago. Why are we doing it again like all these other countries want to do? We should look forward and jump ahead and go directly to Mars. Well, anyway, that sounds more inspirational. Recently, I bought a 4x5 view camera after shooting medium format and 35mm for decades. I thought it might inspire me. Nothing much yet, though. Maybe I should sign up for Mars?
