Even if you're cynical, some marginally effective UHC scheme is in the Democratic Party's best interest as it'd essentially give them one-party rule for a decade or more.
That'd never happen, even WITHOUT the democrat-esque tendency towards self-sabotage.
I mean, throughout the last eight years, we've had 9/11, Katrina, skyrocketing gas prices, a horribly mismanaged economy that led to the worst recession since the Great Depression, two mismanaged wars, and the Vice President
shooting a man in the face. By the end of Clinton's administration, gas prices were low enough that Hummers were considered "cheap", we had a great big surplus, and everyone was genuinely pretty happy. Clinton got impeached, the worst Bush got were a pair wingtips.
The simple fact that the Republicans stood a chance in '08 is outright horrifying. And it doesn't matter what the Democrats do, what good they accomplish, how many millions of people are well-off because of them -- the Republican party at large is such a vile mess of inhuman
scum that they'll do everything in their vast power to destroy the accomplishments and humanitarianism of the Left, including inciting the easily misled or otherwise painfully stupid (many of whom in fact have the most to gain from Democratic policies) into violence.
And the only reason they do this is to keep the money running through their dirty, grimy hands; money they don't even need. You could take some of their money, feed the entire continent of Africa for a year, and each one of those slimy cunts would still have enough money to buy their own personal army of Asian sex-slaves.
