Notice a Pattern?

Anyone else notice a pattern with Obama of consistently setting goals for himself and the country that are completely unmeasurable?

First it was the "create or save" jobs. Everyone admitted there was no way this could possibly be counted. What counts as a saved job?

Next it was the stimulus money, much of which isn't even stimulus. How do we decide that it has done good? So far the only standard is those in favor it saying that it would have been worse without it.

Now Obama has agreed with other G-8 leaders to reduce global warming by 3 degrees over the next...probably 100 years. Again, how is this to be measured? If the temperature does rise by 3 degrees it will be said then it would have raised 6 degrees (i.e. they underestimated how bad it was).

Finally, there is a debate about a second stimulus. Warren Buffett is apparently calling for one as well. Put aside where the money comes from (either taxpayers or you print the money), but how will we measure if it works or not?

Of course, I have already alluded to it, but the common thread among these is the answer is always that it would have been much worse had we not done anything. Obviously this makes sense from a political standpoint, as you cannot be accused of doing nothing, but I thought we were going to get a big dose of hope and change.
