With the Senate lineup currently standing at 52 Republicans and 48 Democrats, the Democrats need at least a three-seat net gain in the 1986 elections, barring unforeseen changes. Thus, there is very little margin for error for the Democratic efforts to regain control. Keep in mind that only three GOP incumbents have been defeated in general elections in the last three elections combined. The retirement of Missouri Sen. Thomas Eagleton and the probable candidacy of GOP Gov. Kit Bond may make the Democrat's job even tougher.
