Polls are tools if you understand them correctly they can give a wealth of insight into an issue. But never take them at face value alone, now what the margin of error means, what the actual questions and answer choices That were used for the poll.
For example, I was once asked to participate in an over the phone poll. I was asked how I thought a certain local politician was doing his job. But rather than being able to say I didn't think he was doing a good job at all, I was only given a choice between a) a good job , or B) a fair job. There was no C) for just plain bad.
Poll questions can also be worded so that they are certain to get the response that the poll taker wants.
Why do they do this? So they can wave a poll in front of you hoping to sway your opinion. Any one in advertising , marketing, and politics knows this, and use it. Some are legit, some are bias, some are just poorly made. You need to know the difference and what they are really telling you.

Polls are only good when they benefit and glorify Democrats, right? They're useless when they indicate that Obama sucks though, or when they indicate that the Democrats are committing economic incest on our nation.

So let's remember to never take them at face value when they indicate that Bush sucks or any leading Republican is performing poorly.....oh wait.....

Get a Grip And Read the Title-- Never Take ANY Poll at face value.
This means Left, Right , Indifferent....
I am simply telling people they need to be cautious and check the facts and information for themselves EVEN if it supports Obama .
For that matter--Never take what any politician whether they be left, right, center or three blocks down the street, at face value. They are there for popularity and votes first, people second.
Media is for ratings and advertisers first, informing you second.
It is naive to believe otherwise.
