The polls

Today there was much talk about McCain being ahead in the polls. Where do they come up with these numbers on who's ahead? I am getting sick of all of this negative news and media that is being covered in the news regarding the presedential and vice presendential runners. Also I feel that the Republicans are doing much to put fear in people in regardingthe Democrats so that the GOP gets the votes. But most people that I talk to are for Obama so I don't even know if these polls are correct. No one came to interview me or anyone I know.
