It doesn't have to be a good choice; it just has to be better than "two per state, no matter what". The perverse incentive there encourages secession, state-splitting, endless intractable battles over Puerto Rican statehood or DC representation, and engineering politics at the state level to influence interstate migrations based partly on political views on national issues. I.e. Colorado decriminalizes recreational cannabis, and Alabama recriminalizes abortion. Lefties are incentivized to move from AL to CO, and righties the reverse. Everybody who voted Doug Jones leaves for literally greener pastures, and mall-menace Roy Moore wins the seat. (Anecdotally, one of my co-workers is moving to Denver, and I have realized I am envious.) It further incentivizes politically competitive states to do anything for just 0.1% of the vote, because that might just be the margin that gets you all the power, for six whole years, on election day.
