“People will vote their pocketbooks”

People will “vote their pocketbooks” (that is, they will vote in their financial best interests) have isolated citations in the 1910s, but became popular after the New Deal legislation of the 1930s. The “vote their pocketbooks” saying became common since the 1950s, when government programs and handouts expanded.
 
The term “pocketbook issue” was used in 1900 and became popular in August 1924, when Calvin Coolidge said that he’d run for president on pocketbook issues.

The undesirability of having men in the senate who might vote their pocketbooks in a speculative enterprise affecting Central American republics is shown by the history of the treaties negotiated by Secretary Knox with Honduras and Nicaragua.

Few like to go back after tasting the wine of life in the world’s political, financial, and military center. And if they do, their wives do not. So they are tempted to vote their pocketbooks rather than their convictions.

Handout Programs, Once in Effect, Are Hard to Change
In any discussion of the fall elections, the cynical opinion is often expressed that “people will vote their pocketbooks”, meaning they will vote for continuation of the many handout programs introduced in the last twenty years, and therefore will give their votes to the Democratic candidate.

Even the so-called “farm revolt” of 1948 does not prove that farmers vote their pocketbooks; for farmers were deeply split in that election, with Mr. Truman—who was running, it might also be recalled, on a flexible parity platform—losing as many farm states as he won, and winning others only by virtue of his vote in the cities. I think most objective observers would agree that those farmers—by no means all—who did express a preference for Mr. Truman over Mr. Dewey and for Mr. Eisenhower over Mr. Stevenson, were motivated by more than promises of financial assistance.

When They Vote Their Pocketbooks
Published: April 08, 1988
While the 1988 campaign flickers and flares on TV screens and front pages, the engines of political decision making churn away below the surface. In which direction do they push? Ask any analyst what motivates voters and the answer is always the same: their pocketbooks. By that standard, things seem headed steadily Republican.

Susan Estrich: People Will Vote Their Pocketbooks

LOS ANGELES —  It’s still the economy, stupid.

The conventional wisdom is that, unless we’re at war, people will vote their pocketbooks. And if they’re worried enough, they may vote their wallets even in the face of war. Patience may work for the richest of the rich, but they don’t decide elections.

“Voters vote their pocketbooks.” It’s a famous expression, and a political axiom that politicians who want to survive, don’t forget. They don’t vote their deficits. (See, it even sounds silly saying it, and writing it.)
