By comparison, just 6% of Democrats and Democratic leaners agreed with the movement, while 25% disagreed (31% had no opinion and 37% had not heard of it).

While support declined in subsequent years, roughly a third or more of Republicans continued to express agreement with the movement for the next several years. By fall 2015, the share of Republicans who said they agreed with the tea party had dropped to 28%.
