We all know the limits of online "polls." There's no random sampling, zealots can skew the results, and so on.
But the poll of most- and least-favorite achievements of the Obama administration that has just gone up on Ranker is more interesting than most, mainly for the list of choices it presents. I know that this is the season for assessments of the president (including our own) and for detailed analyses of what he has gotten right and wrong. I found this one valuable for collecting in one place a wide range of the Administration's results. It's worth a look.
