They're actively trying to prevent people from enrolling, down to the level of asking for pledges. This continuing sabotage works in multiple ways. The negative advertising continues to make the ACA seem like a bad thing, and if they're successful in preventing people from signing up, they can help ensure that it actually has a harder time shaping up. And yet, the Kochs still do all of this mostly from the shadows. The average American doesn't know that "Americans for Prosperity" or "FreedomWorks" exist, and if they do, they just think they're patriotic-sounding organizations.
It makes you wonder exactly what's in it for the Kochs if a bunch of Americans don't have affordable health care. What good does a bunch of sick, bankrupted Americans to the Kochs? Or is it enough to try to make the President look bad? And there's a deeper question I keep coming back to, with the Kochs, Sheldon Adelson, Foster Friess, Rupert Murdoch and so many of these conservative billionaire benefactors: why do these impossibly rich old men care so much about being just a bit richer? You know what, at least George Soros contributes to causes that don't line his already stuffed pocketbook.
