The result of the effort over the next two weeks could result in the more-vulnerable candidates getting less help from the national party than those with a better chance of winning re-election in contested districts, The New York Times said Sunday.
The strategy is to identify the top two-dozen candidates with the best chance of prevailing in November. That would enable the Democrats to maintain a slim majority in the House.
"We are going to have to win these races one by one," said Rep. Chris Van Hollen of Maryland, chairman of the Democratic Congressional Campaign Committee.
The Times said Van Hollen conceded that some incumbents could be basically cut loose if an examination of polls and other data over the next two weeks shows them to be a lost cause.
