They are not planning to lose. They want to win. But it looks to me like they were told that Trump would “lose” in Georgia and they would “win” no matter what the voters did, using various kinds of fraud. Some Republicans (like Kemp and Raffensberger) probably did things (Dominion contract, illegal consent decree) to help make this happen. Not sure if Perdue and Loeffler “helped” but if they were aware of this deal and didn’t tell anyone, they are implicated. Now it appears that the Dems are pulling out all the stops in Georgia and might not honor the deal to send the Republicans back to DC. However, if Loeffler and Perdue knew about it, too late for them to do anything now. They are stuck and must be praying they will in fact go back to the Senate, since praying is about all they can do....
Yes, about three days after the general election, Georgia Republicans began getting pelted with money-seeking messages from Perdue, Loeffler and Kemp. "Save Georgia!" was the cry. Now, there hadn't been a word from any of them about the fraud being used against Trump before then. Obviously they realized that the Dems were going to keep pushing and grab their senate seats, hence the belated cries for help.
