Some big names are hot for George Stephanopoulos‘ ABC Sunday morning “This Week” spot now that he’s been named “Good Morning America” anchor. ABC White House correspondent Jake Tapper is vying with “Nightline” co-anchor Terry Moran amid rumors an approach may be made to “Washington Week in Review’s” Gwen Ifill. Although Stephanopoulos hasn’t said he’ll leave “This Week,” a source told us, “George wants to carry on his Sunday show, but there’s a feeling he may end up giving it up through tiredness. And there are already people lining up to take his place.”
