A report on Democratic Party (United States), Franklin D. Roosevelt, Republican Party (United States) and Gallup (company)

Its main political rival has been the Republican Party since the 1850s.

As a member of the Democratic Party, he won a record four presidential elections and became a central figure in world events during the first half of the 20th century.

Since the mid-1850s, it has been the main political rival of the Democratic Party.

Since Franklin D. Roosevelt and his New Deal coalition after 1932, the Democratic Party has promoted a social liberal platform.

Gallup also refused to conduct surveys commissioned by organizations such as the Republican and Democratic parties, a position the company has continued to hold.

In 1936, Gallup successfully predicted that Franklin Roosevelt would defeat Alfred Landon for the U.S. presidency in direct contradiction to the popular The Literary Digest; this event popularized the company and made it a leader in American polling.

In the 1932 presidential election, Roosevelt defeated Republican incumbent Herbert Hoover in one of the largest landslide victories in US history.

The GOP lost its congressional majorities during the Great Depression (1929–1940) under President Franklin D. Roosevelt, whose popular New Deal programs shifted the country towards the Democratic Party for most of the next three decades.

Based on a poll conducted in 2014, Gallup found that 30% of Americans identified as Democrats, 23% as Republicans, and 45% as independents.

According to a 2015 Gallup poll, 25% of Americans identify as Republican and 16% identify as leaning Republican.

A late August poll taken by Gallup found the race to be essentially tied, but Roosevelt's popularity surged in September following the announcement of the Destroyers for Bases Agreement.
