Byron York's story from this morning looks pretty gloomy for the Democrats:

Here in Massachusetts, as well as in Washington, a growing sense of gloom is setting in among Democrats about the fortunes of Democratic Senate candidate Martha Coakley. "I have heard that in the last two days the bottom has fallen out of her poll numbers," says one well-connected Democratic strategist. In her own polling, Coakley is said to be around five points behind Republican Scott Brown. "If she's not six or eight ahead going into the election, all the intensity is on the other side in terms of turnout," the Democrat says. "So right now, she is destined to lose."

... until you get to this part at the end:

With the election still four days away, Democrats are still hoping that "something could happen" to change the dynamics of the race. But until that thing happens, the situation as it exists today explains Barack Obama's decision not to travel to Massachusetts to campaign for Coakley. "If the White House thinks she can win, Obama will be there," the Democrat says. "If they don't think she can win, he won't be there."

He'll be there. So does that mean she has a chance?
