"Gloomy top Republicans in Virginia are privately predicting that a man named 'Warner' will be elected to the Senate from their state next year, but add that he is likely to be a Democrat," according to Robert Novak.
"The state's GOP leaders not long ago were sure that 80-year-old Republican Sen. John Warner would seek a sixth term in 2008, but now they think he probably will not. That would open the door for Democratic former Gov. Mark Warner (no relation) to enter the race. Any Republican would be an underdog against the Democratic Warner."
"Rep. Tom Davis is the leading prospect if John Warner doesn't run, but conservatives are seeking somebody to oppose Davis' nomination."
