If there is a next election, Bibi needs to make sure there are other secular right wing parties for people to vote for (especially if there is an indictment hanging over him).
There were too many center/right voters who couldn't get themselves to vote for Bibi, yet wouldn't vote for a religious Yamina party. Those votes defected to Lieberman, or even Blue and White. Arguably, all of Kachlon's voters (and Kachlon was no fan of Bibi to begin with,as that originally caused him to break away from Likud and make his own party) didn't vote for Likud and instead looked elsewhere. But with no other alternative than Lieberman or Blue and White, they voted there.
So he needs to make sure there is a secular right party, whether its Kachlon or Shaked ect, that can pass the threshold, yet unlike Lieberman, will join him, and won't be anti chareidi. There are too many voters who are ok with Bibi, yet aren't running to vote for him, and need a platform to vote for a center/right party.
Otzma, only costed the right 1 seat in the end, but they shouldn't run, and instead merge with the religious right, and add 2 seats there.
