3. Rasmussen's daily tracking polls have a 4 percentage point margin of error
Daily tracking results are collected via nightly telephone surveys and reported on a four-day rolling average basis. Each update includes approximately 900 Likely Democratic Primary Voters and 800 Likely Republican Primary Voters. Margin of sampling error for each is +/- 4 percentage points with a 95% level of confidence.

That means that Hillary Rodham Clinton could be beating Barack Hussein Obama by 48% to 40% or vice versa, either claim being possible within the margin of error quoted. Therefore you are adding meaning to what basically amounts to statistical noise. The trend you are talking about doesn't exist, statistically speaking, and since you quoted the stats, don't complain to me for pointing out the error.
