One rainstorm, two campaigns and two responses

Wearing jeans, white sneakers and an insulated windbreaker, Barack Obama delivered his stump speech this morning in a chilly, steady rain in Chester, Pa.

"A little bit of rain never hurt anybody," Obama said, surveying the soaking, umbrella-covered crowd at Widener University, occasionally rubbing his hands together for warmth and squinting through the raindrops.

Obama took the stage less than an hour after the McCain campaign announced it was postponing a rally at 1:15 p.m. in Quakertown, Pa., about one hour north of Chester, "due to weather."

The Obama campaign considered moving its event inside, but couldn't find an appropriate venue, an aide said. An estimated 9,000 people turned out.
