CLEAR LAKE, Iowa (AP) - Nearly all the Democrats running for president are descending on northern Iowa to make personal pitches to hundreds of would-be supporters in the state that kicks off presidential primary voting.

Around 20 candidates are speaking at Friday night's Wing Ding, an annual fundraiser featuring chicken wings in Clear Lake, population about 8,000.

The event coincides with the state fair in Des Moines, and most White House hopefuls have been crisscrossing Iowa for days, some by bus or RV.

Former Rep. Beto O'Rourke canceled his planned Iowa visit to remain in his hometown of El Paso, Texas, where a mass shooting killed 22 people.

O'Rourke said Friday on Facebook that he'll attend more funerals and continue hospital visits, but will rejoin the campaign "at some point" and "sooner or later."
