Here is Gallup:
WASHINGTON, D.C. — Americans’ desire for a third party has ticked up since last fall and now sits at a high in Gallup’s trend. Sixty-two percent of U.S. adults say the “parties do such a poor job representing the American people that a third party is needed,” an increase from 57% in September. Support for a third party has been elevated in recent years, including readings of 60% in 2013 and 2015 and 61% in 2017.
Meanwhile, 33% of Americans believe the two major political parties are doing an adequate job representing the public, the smallest percentage expressing this view apart from the 26% reading in October 2013.
The latest results are from a Jan. 21-Feb. 2 poll. The survey was conducted before recent news reports that dozens of government officials in prior Republican administrations were in discussions to form an anti-Donald Trump third political party.
