Obama regains lead in polls, should we care?

The Media is constantly pushing polls on projected election outcomes and the American people have developed an unhealthy craving for more. The most recent polls show Obama regaining his overall lead with voters as he pounds John Mccain (who seems to be pounding himself as well) on his lack of economic strategy. As Wall Street continues its unprecedented downward spiral the economy is most likely going to become far and away the most important issue on the table. However, the most recent polls are most likely not a result of Obama's progress in the debate over the economy (that will come later). Sarah Palin's convention-inflated approval ratings are dropping steadily as the media puts her under its stage lights.
But my point is not what is driving these polls, but why we shouldn't care. These national polls are not an indication of what will happen on Novermber 4th; so much more can and will happen before election day that will invalidate them. And most importantly, the election is not based on popular vote. The electoral college will decide the winner of this election, which means that if we are to check polls as progress reports we should look to battleground states like OH, FL, PA, CO, NV, NH and MI among others. These are the states that will decide the election, not polls that include oregon, california, texas, or kansas.
