Welcome to the beat. I am Ari Melbra and this is the final Friday until the elections.

We head into the weekend campaigning four days out from election day and the campaigns are

bringing out some of the big guns.

I said it was up to the citizens of Pennsylvania and of course, but I will tell you all this.

If I lived in Pennsylvania, I would have already cast my vote for John Federman for many reasons.

There it is. That's Oprah pushing Democrats in the key battleground state of Pennsylvania.

We can report that tomorrow there will be rallies there with Biden, Trump and Obama.

So if you think about it, if there's one thing both parties do seem to agree on right now on this final Friday heading into the midterms weekend,

it is that Pennsylvania is clearly important.

Important because it's close and it could decide control the entire US Senate.

Now Oprah's appearance is not just about rallying Democrats, although she's been an Obama endorser for some time.

It also is striking because it is her very direct effort to draw a public line in government against someone that she famously embraced in media and business.

Dr. Oz's whole career and current prominence really stems from Oprah elevating the doctor from guest to peer.

End of doing about eight, about 88 children.

88 children, of course, in my career.

Here, of course, I know she's coming out of the show.

Dr. Oz, turn around here and look at this wall. There's the wall.

On that wall are all these faces and these are just some of the people who told us that something they heard you say on the show, saved their lives.

It's like my son grew up and has his own show.

He left home. You're doing all right, son.

Well, that is the history and for many Americans who watch less news and more afternoon TV and Oprah's beloved in so many households, those are long memories, including in Pennsylvania.

So why is this part of the top story tonight? Well, I told you this race could define the whole Senate control.
