There's another reason why the Republicans and Blue Dogs want to delay healthcare reform. Sure, if they delay long enough, the 2010 midterms will strip away the political balls for reforming the system. But also, while reform is further delayed, the bullshit crazy talk has more time to leach into the minds of voters and thus providing voter support for the delay.
With every day that goes by, more and more voters can potentially be convinced (despite their better interests) to believe insane anti-reform attacks -- like the one about killing old people or the classic socialism thing or the most ridiculous argument of all: shielding private insurers from the evil competition of the public option.
Meanwhile, 14,000 people are losing their healthcare every day. Now if this was due to terrorists blowing up health insurance policies with tiny explosives, healthcare reform would've been passed months ago.
