In the aftermath of Fidel Castro’s death and the election of Donald Trump, Americans continue to express support for the recent thaw in U.S.-Cuba relations. Yet the U.S. public remains skeptical about whether the island nation will become more democratic in the coming years.

Three-quarters of U.S. adults (75%) approve of the decision last year to re-establish U.S. relations with Cuba, while nearly as many (73%) favor ending the long-standing U.S. trade embargo against Cuba, according to a new national survey by Pew Research Center conducted Dec. 1-5.

These views are similar to attitudes about U.S. relations with Cuba in July 2015, following the decision to renew diplomatic ties. At that time, 73% approved of the re-establishment of U.S diplomatic relations with Cuba, and 72% favored an end to the trade embargo.

From the 2019 Florida International University poll executive summary


A large majority (63%) supported the decision to open
diplomatic relations with Cuba, with post-1995 arrivals
and second and third generation Cuban Americans
strongly backing the Obama era policy shift (75% and
77% respectively). Support for the reestablishment of
diplomatic ties maintains a solid majority among all age
groups up to age 76 and above, after which it drops to
a 31% support. A majority (61%) of registered voters
express support while this figure balloons to 77% among
non-registered voters (Figure Cluster 7).

A strong majority of respondents (57%) favors the
lifting of travel restrictions impeding all Americans
from traveling to Cuba. Unsurprisingly, the newer
arrivals and those not born on the island lead the
charge in supporting unrestricted travel (68% and
69% respectively) while the pre-1980 migrants oppose
free travel by almost the same proportion (63%).
Approximately 55% of registered voters also favor
unrestricted travel by all Americans (Figure Cluster 9).
Similarly, 65% of the respondents support the
continuation of “people-to-people” travel opportunities
currently endorsed by U.S. policy, with all age cohorts,
except for the 76 and above cohort, expressing majority
support. Sixty two percent of registered voters favor the
policy as well (Figure Cluster 11).
