I don't know if they are FF or HP, but I know they've done more to advance SCIENCE than every HP voter in this thread combined.
Who cares?
The people who have had their lives lengthened? The Scientists getting paid? Everybody that cares about both of those groups? Lots of people.
A better question would be, what have they done to advance science? I haven't heard anything about that.
Anyway, no matter what they have done, I'm almost positive they're actions to undermine the federal government would set back science by a lot more than they could possibly advance it if they got their way. I can't even think of a single worthwhile scientific advance in the last century that wasn't primarily government-funded, though I'm sure there have been quite a few, since I'm not an expert on the topic. Still, I'm quite certain that the public sector does much more than the private sector to advance science in this country, based on what I do know.
Mega-HP's, for anyone who hasn't figured out my opinion already, but not all that influential on their own when it comes down to it. They're just two of the most prominent example of one of the biggest threats to democracy in this country.
