A federal appeals court ruled that former House Majority Leader Tom DeLay's name must remain on the Nov. 7 ballot even though he withdrew from the race for his Texas congressional seat. The decision, which affirmed a prior ruling, may force DeLay to either campaign for the Houston-area seat he wanted to abandon or concede it to Democratic candidate Nick Lampson. ``In situations such as the one before this court, a replacement candidate cannot appear on the ballot if the original candidate merely withdraws,'' Judge Fortunato Benavides wrote for the three-judge panel. The ruling is a setback for the Texas Republican Party, which argued that it should be able to replace DeLay because he withdrew from the race and announced he was moving to Virginia after he won the March 7 party primary.
