Bush is now talking about a "time horizon" for bringing the troops home from Iraq — not a timetable like Obama has been saying because Obama can't be allowed to say, "I told you so!" A time horizon seems to at least contemplate an end to the war. Maybe Bush is thinking about his legacy and he finally gets it. Will McCain adopt Bush's "time horizon" or stick with his 100-year plan?
