The candidate whose ascendancy convinced lawmakers of the urgency of health care may not be curable. A poll released today shows Pennsylvania's Democratic Sen. Harris Wofford trailing Republican challenger Rep. Rick Santorum by 10 percentage points. Just two years back, Wofford won the seat, beating GOP nominee Dick Thornburgh in an upset by promising to make health care a priority. The Keystone Poll of likely voters, conducted over the weekend, showed the Republican ahead 42-32, with 23 percent of all voters still undecided. But don't close the book on Wofford: Santorum's tracking polls show the race a statistical dead heat.Post your opinion on theWashingtonbulletin board.Post to Elections "'Senate Predictions."
