The Republicans opposed the stimulus bill because THEY'RE AFRAID IT MIGHT HELP.
They oppose national health care because THEY'RE AFRAID IT MIGHT WORK.
They're afraid that if the government actually helps people, the Democratic Party will benefit, just as it did in the 1930s and 1940s.
Their ONLY chance of getting back in power is if the economy utterly crashes and people suffer needlessly.
The Republican leadership WANTS people to suffer. The right-wing politicians and hate radio pundits DON'T GIVE A DAMN ABOUT ORDINARY PEOPLE.
The Republican goal is a nation where the vast majority of people are beaten down and completely submissive to the orders of a wealthy oligarchy--a conservative oligarchy that uses the rest of the country as its own personal garbage dump.
So they'll fight everything that benefits the average American, and I mean everything.
It's what the conservatives are best at. Hell, it's the ONLY thing they're good at.
