You have 2 stocked lakes and 2 gals decide to have a fishing contest.
Lake one is 5 sq miles and has been stocked with 60,000 fish. Lake 2 is 500 sq miles and has 12,000 fish.
Now the gals decide that their friends want to take part so now each team has 2 boats. They can decide where to put the boats to be most effective. Since 5 out of every 6 fish are in lake one, lake two remains untouched. Besides, lake two has weeds, submerged hazards and a lot of places fish can't live and boats can't reach. Lake one is custom made for boats and fish are every where.
The gals would have to be idiots to waste one of their very two boats in the large lake where there are very few fish. As would any politician and her/his running mate's precious time in the less populated state.
In 2012, 24 of the nation's 27 smallest states received no attention at all from presidential campaigns after the conventions. They were ignored despite their supposed numerical advantage in the Electoral College. In fact, the 8.6 million eligible voters in Ohio received more campaign ads and campaign visits from the major party campaigns than the 42 million eligible voters in those 27 smallest states combined.
The indefensible reality is that more than 99% of presidential campaign attention (ad spending and visits) was invested on voters in just the only ten competitive states in 2012.
Two-thirds (176 of 253) of the general-election campaign events, and a similar fraction of campaign expenditures, were in just four states (Ohio, Florida, Virginia, and Iowa).
There are only expected to be 7 remaining swing states in 2016.
With National Popular Vote, candidates would have a reason to poll, visit, advertise, organize, campaign, and care about the voters in every state.
In a nationwide election for President, candidates would campaign everywhere—big cities, medium-sized cities, and rural areas—in proportion to the number of votes, just as they now do in only the handful of battleground states.
In the 2012 general-election campaign
Florida (29 electoral votes) had 40 events
Pennsylvania (20 electoral votes) had 5
Michigan (16 electoral votes) had 1
Ohio (18 electoral votes) — had 73 (and a similar fraction of advertising expenditures).
The candidates campaigned in various parts of the state essentially in proportion to its population.
● The 4 biggest metropolitan statistical areas (MSAs) in Ohio have 53.9% of the state’s population and received 52.1% of the state’s 73 campaign events in 2012—slightly less than their share of the population (but very close to their percentage of the population). They voted 54% Democratic.
● The 7 medium-sized metro areas have 23.6% of the state’s population and received 23.3% of the campaign events—almost exactly in proportion of their population. They voted 52% Democratic.
● The 53 remaining counties (that is, the rural counties lying outside the state’s 11 MSAs) have 22% of the state’s population and received 25% of the campaign events—slightly more than their share of the population (but very close to their percentage of the population). They voted 58% Republican
In a nationwide election for President, candidates would campaign everywhere—small states, medium states, big states, big cities, medium-sized cities, and rural areas—in proportion to the number of votes, just as they now do in only the handful of battleground states.
The main media at the moment, TV, costs much more per impression in big cities than in smaller towns and rural area. Candidates get more bang for the buck in smaller towns and rural areas.
