This is massively less likely than sorting out the Electoral College, but imagine for a minute that 100 Senators woke up tomorrow and decided to do the right thing.
Dianne Feinstein, the senior Senator from California would wield 6.04 votes. Mike Enzi, the senior Senator from Wyoming would have to make do with 0.09 votes.
Overall a party line vote would see 55.85 Democratic votes to 44.15 Republican, assuming normal independent caucusing habits. Not quite a supermajority, but enough to not send Kavanaugh to The Supreme Court for instance.
This is based on 2010 census figures from Wikipedia.
Not going to happen, but find my estimate of your State's fair voting power by Senator below.
