Just to illustrate the inherent money advantage the Democratic nominee is likely to have: in the past 4 Maine Senate elections, the winner spent an average of $11.75 per vote earned. A general rule of thumb is that anywhere from $5 to $10 per vote is needed in order to run a competitive and viable campaign; Maine, however, is a relatively small state, hence the increased average per vote spending.

the Democratic nominee in 2020 will start out with the equivalent of $11.10 per voter needed for a majority (based on 2016 total votes; $4.16 million for 373,964 votes).
