There are "easily 95 to 100" House seats in play on Nov. 2, the head of House Republicans' campaign efforts said Thursday.

Rep. Pete Sessions (Texas), the chairman of the National Republican Congressional Committee (NRCC), said that his party was already poised to pick up a portion of those seats totaling in the "low 40s," with another 60 or so races that wouldn't be decided until Election Day.

"Within the margin of error, I would say there are easily 95 to 100 seats," Sessions said on ABC's "Top Line" webcast. "Those other 60 seats will be within the margin of error all the way to Election Day, and turnout will decide that."

The prediction by Sessions is consistent with his previous suggestion that Republicans would make inroads into Democrats' House majority totaling in the 40s, though it also opens the window to potentially much larger gains if Republicans have a good day on Nov. 2.

House Minority Leader John Boehner (R-Ohio) had said earlier this year that as many as 100 seats were in play, and outside projection services monitoring the campaign have named dozens of competitive races.

Democrats have expressed confidence that they'd hold off losing the net 39 seats or more that the GOP needs to regain the majority. House Speaker Nancy Pelosi (D-Calif.) said Wednesday night that she has "every anticipation" that Democrats will hold the House and that she will stay on as Speaker.

Pelosi also said she wouldn't want to trade positions with Republicans at this stage, with only 12 days remaining until voters head to the polls.

"If she's proud of her hand, I would sooner be us," Sessions responded Thursday.
