Gingrich cancels book signing in Washington

WASHINGTON (AP) ? Newt Gingrich has canceled the latest of his book signings that are as much of his presidential bid as campaign speeches.

Gingrich’s campaign on Friday released a statement from a news stand inside Washington’s Union Station that cited safety concerns. But Gingrich has also faced questions about a campaign strategy that seems to straddle winning votes and earning dollars.

The scheduled book signing by Gingrich and his wife, Callista, was the campaign’s only public event of the day. The former House speaker’s rivals, meanwhile, were busy campaigning in the traditional early voting states.

Gingrich prides himself on his nontraditional campaign style. It isn’t clear whether it will pay off politically. But it certainly has not hurt his own income.
