Best case scenario for GOP-- lose IL, hold AK, CO, OK, gain NC, FL, SC, GA, SD, LA for a gain of 5, going from 51 to 56, still short of the Democrat filibuster margin
Worst case for GOP -- lose IL, AK, CO, OK, gain only GA. Drop from 51 to 48 seats, return Daschle to majority leadership in name
It's anyone's guess -- between 48 and 56 seats then.
That would be a gain of six if the GOP took LA, FL, GA, SC, NC, and SD. Or 57 seats, absolute best hope
