Sorry to be so uninformed about the process, but what does this mean? That 58 votes (I assume FOR Alito) are enough to break up a filibuster? And what's happening in Dakota and Arkansas?
North Dakota has two Democratic senators with one up for re-election this year. North Dakota is a heavily Republican state and a vote against Alito would create a backlash. The same for South Dakota senator, Time Johnson (D). South Dakota, too, is a heavily Republican state. Arkansas has two Democratic senators, but it's a state that continues to trend Republican. All five senators have not yet said how they will vote if a potential filibuster came about or on Alito himself.
