I really don't get this

DNC Chair Refuses To Acknowledge Bernie's Effect On Dem Election | The Daily Caller

"In the 2008 election cycle, the Democratic Party had 26 total debates which Schultz argued spread the candidates too thin."

Here’s an interview of DNC Chair Debbie Wasserman Shultz by Andrea Mitchell of MSNBC in which the Shultz person says the 26 Democratic debates during the 2008 election cycle “spread the [Democratic] candidates too thin."

Too thin for what? She’s taking about the Democratic candidates for president, and didn’t the Democrats win that office in 2008? On this planet? So in what way did those debates damage the party? 

I don’t get it.

(I guess Andrea Mitchell understands this because she didn’t ask. But she’s not telling.)
