Oh, sure. 70% of Americans support space efforts.
[sarcasm]That's why it has been much a big political issue for the past several campaigns. Hell, you couldn't turn on a TV or radio without being bombarded by political ads by candidates promising to build moon bases, missions to Mars, and NEO search programs.[/sarcasm]
Show me a poll from a credible source that backs up your claim of 70% support. I'd love to see it because maybe then we'd be able to lobby for increased funding to modernize the antiquated stovepiped systems we're stuck with today.
