Gallup Poll suggests 68% of adults will vote, a very high percentage in a nonpresidential election

From The Wall Street Journal Online morning brief:

If the anger over the war in Iraq -- and whether it has worsened or improved U.S. counterterror efforts -- has helped fuel one of the nastiest and expensive midterm campaigns, it has also aroused voters' interest to the highest level in a long time. The Los Angeles Times notes that the USA Today/Gallup Poll released this week suggested 68% of adults were "absolutely certain" they would vote, "the highest level of interest Gallup has recorded for a nonpresidential election in the half a century it has measured American opinion."
