Why change our rhetoric every four or eight years? I favor raising expectations no matter who's in power.
That said, yes, my experience with organizing for the Labor Party is that when the dems are in power, people can see that they aren't the solution. With Bush in, there's too much defensive work--in the unions and everywhere else--to even think about an alternative party. It's a fine example of the general case that being more downtrodden doesn't automatically lead to more revolt--and, for me, more evidence that there's frequently no conflict between reform and revolution.
