The have a host of excuses so we can't just say they would blame Russia.
1) Russia
2) Gerrymandering
3) Voter suppression
4) Trump had the voting machines rigged
5) Republicans got into Democrat areas and closed polling places.
6) Voter-ID
7) Republicans purged voters off the voter rolls.
If Republicans do well tonight, we just have to bet on which excuse they will use this time.
