A Lack of chemistry is already plaguing CNN’s new morning show “Early Start” as it attempts to gain footing one month after the launch. Hosts Ashleigh Banfield and Zoraida Sambolin “have expressed frustration about the schizophrenic nature of the show,” a source said. Another source said they just don’t gel — Banfield talks too much, Sambolin doesn’t say enough. Meanwhile, executives are looking to support Soledad O’Brien — who anchors the following morning show “Starting Point” solo, with a regular crop of panelists — and have expressed interest in adding conservative commentator Will Cain and CNN analyst Roland Martin to the cast. We also hear that executives are thinking about developing an 11 p.m. show. A network rep denies this, adding, “We couldn’t be more pleased with Soledad and the direction she is taking her program. Her newsmaking interviews and substantive panel discussions are the centerpiece of the program. Ashleigh and Zoraida are doing great.”
