Stephen King has a special Halloween request for voters: helping him end the “nightmare” he calls the GOP majorities in Congress.

In an e-mail with the subject line “I know scary,” King asks members of MoveOn.org to help organize pre-Halloween phone parties this weekend. At the parties, attendees will call “progressive” voters in key districts to remind them to vote Nov. 7.

“If I know anything, I know scary,” he writes. “And giving this president and this out-of-control Congress two more years to screw up our future is downright terrifying. Thankfully, this national nightmare is one we can end with — literally — a wake up call...

“And since it’s Halloween, we’ll celebrate with an optional costume contest, some pumpkin carving (I’ll be making a Jack-Abramoff-O’Lantern) and—of course—plenty of candy,” he adds.
