Where's the plurality?

The New York Times continues the Democrats are in Trouble meme today with a front page story declaring "Democrats Long-Held Seats Face GOP Threat," declaring "nearly a dozen well-established Democrats" face a serious challenge.

Problem is I read the story once and scanned it numerous times and couldn't find "nearly a dozen." Maybe nearly a half-dozen, with a focus on one in particular.

Washington is an increasingly insular and alien place for many Americans, to be sure. It's laudable the Times ventured outside the Beltway to check on one of two districts. But a trend worthy of such a definitive Page One headline?

Maybe inside the Beltway. But I need a lot more proof.
