You need to understand a couple of things about how polls work.
First, this poll has a margin of error of + or - 4%. This means that even according to this poll's results, Dean's support may be as high as 50% or as low as 42%, and Bush's support may be as high as 55% or as low as 47%. So, even according to this poll, Bush could have a lead as large as 13%.
Second, even this rather broad spectrum of possible results (like all scientifically conducted polls) has a 95% likelihood of being accurate. To understand what this means, think about a basketball player who has a 95% probability of making a freethrow--he misses one out of every twenty times. So, while 19 out of 20 such polls do capture real public attitudes somewhere within their margins of error, 1 out 20 polls simply miss the mark. If this is that twentieth poll which is wrong, which fails to capture reality within its margin of error, then Dean must in actuality have less than 42% support (I am assuming he can't possibly have more than 50%). To know whether this is the 1 out of 20 polls that is just plain wrong, we need to compare it to similar polls. Other polls asking the same question in the last few weeks have shown Dean with support in the low 40s or high 30s, and Bush with a 12%-20% lead (+ or - some margin of error--usually between 3% and 5%, depending on the particular poll's sample size). This poll therefore appears to be incorrect.
Third, we then are left with two possibilities. (1) Something has happened in just the past week or so to give Dean a huge boost after all the other polls had been taken, and that real boost is reflected only in this new poll; or (2) this poll is simply one of the few wrong ones. Since I can't think of any reason to think (1) is true, my guess is that it is (2). In fact, there is a good reason to believe that (2) is true--and this poll is just wacky. Scientific phone polling is becoming increasingly difficult and inaccurate as more and more people are not home, screen calls, refuse to answer polls, etc. These factors mean that the people who do answer the polls are not truly representative of the overall population. And all these problems become more extreme during a holiday. Holiday polls always yield questionable results--particularly since Republicans are less likely to be home than are Democrats.
So, in sum, I bet these results are not being emphasized by Time or CNN not because of a conspiracy against Dean, but rather because the poll is likely just wrong. They don't want to lose credibility by promoting a mistaken poll.
