Binyamin Netanyahu issued a late call to Likud voters to get out and vote after it became clear that there are very high turnouts in much of Israel, but lower than expected in some Likud strongholds. There are also early indications that Yair Lapid's new Yesh Atid Party is doing very well.
None of this is reason to expect an upset; by almost all estimates, Likud will still be he biggest party. A resurgent center might, however, persuade Netanyahu to form a center-right coalition rather than a hard-right one. But I won't speculate further here; we'll soon know the results.
