I think we are polled out. Most of this stuff is making about as much sense as the economy.
I think you are right! How you can take a poll of, say, "1600 voters nationwide" (which is not untypical), and then tout the results as indicative of any "trend" is just beyond me, even with adding in the "weighting" factors (which I'm as dubious about as the "sampling" much of the time, LOL!)...
