Many retailers have more than the usual riding on sales beginning this Thanksgiving weekend.

The presidential election pushed holiday shopping later than usual because some toy and game makers held off on their big introductions for maximum attention. The aftereffects of Hurricane Sandy have included logistics problems and merchandise delivery delays. And some retailers, trying to keep inventory lean during uncertain economic times, have given themselves little room for error: shipments of holiday toys, for instance, are down 13 percent this year, to the lowest level since 2007, according to the global trade research firm Panjiva.

All of that makes for a particularly strange holiday season, retailers and analysts say.

“The election sucks all of the oxygen out of the room in terms of attention,” said Eric Hirshberg, the chief executive of Activision Publishing, the video game company. “A lot of the best media inventory goes to the candidates. It gets more expensive because there’s this premium demand from the candidates.”

Hasbro is adding more shades of its Furby toy through the end of the year, and Mattel last week introduced a new Monster High video game. Last year, Activision introduced its big Call of Duty release in early November. This year, though, it did not release Call of Duty: Black Ops II until Nov. 13.

“We were also worried that if we released Call of Duty before the election, no one would show up to vote,” Mr. Hirshberg said. (He was speaking facetiously, but given that the game’s retail sales were more than $500 million in the first 24 hours after it made its debut, he may have a point.)
