Welcome to Pollapalooza, our weekly polling roundup. Today’s theme song: “Makin’ It” from the television show “Makin’ It.”

Poll of the week

As a humanitarian crisis unfolds in Puerto Rico after Hurricane Maria devastated the island last week, the U.S. government’s response has been criticized, and much of the mainland news media has been focused on other issues. Polling shows that many Americans don’t know a lot about the U.S. territory, but as they learn more, the focus may shift in the mainland’s response.

Last year, YouGov found that only 43 percent of Americans knew Puerto Ricans were U.S. citizens. A poll conducted after Maria by Morning Consult showed that number may be up, but only slightly: Just 54 percent of Americans knew Puerto Ricans were U.S. citizens.

Morning Consult also found a relationship between how much people knew about Puerto Rico and how much they supported post-Maria aid. Among Americans who knew Puerto Ricans were U.S. citizens, about 8 in 10 supported government aid, compared to just 4 in 10 people who did not know. Overall, 64 percent were in favor of aid to the island.

Don’t be surprised if that overall percentage goes up, especially among Trump supporters, as more Americans learn that Puerto Ricans are U.S. citizens. That 64 percent in favor of aid increased to 68 when respondents were informed that Puerto Ricans are U.S. citizens. Trump backers specifically saw a 10-point jump — from 57 percent to 67 percent — in favoring aid when told that Puerto Ricans are U.S. citizens.

For comparison, 80 percent of Americans said they approved of a $62 billion relief package passed and signed into law after Hurricane Katrina, according to a Pew Research Center poll.

Other polling nuggets

Americans hated Graham-Cassidy — Republicans may have caught a break when their latest Obamacare repeal effort failed. A number of polls came out this week (see the chart below) showing that far more Americans opposed Graham-Cassidy than supported it, generally by more than 20 percentage points. When asked directly about a comparison of the two in an ABC News/Washington Post survey, 56 percent preferred Obamacare to Graham-Cassidy, while 33 percent favored the GOP bill.

Trump’s job approval ratings

Trump’s job approval rating is 38.8 percent; his disapproval rating is 55.1 percent. It’s the first time since we started Pollapalooza that Trump suffered a week-to-week decline in his popularity. Last week his approval rating was 39.5 percent, while his disapproval rating was 53.6 percent. The downtick in Trump’s approval rating may be tied to him dominating the news with his feud with the NFL, after he had kept a lower profile for a few weeks.

The generic ballot

Democrats lead Republicans 46.1 percent to 38.1 percent on the generic congressional ballot. That’s about the same as it was last week when Democrats were ahead 46.4 percent to 38.6 percent.

CORRECTION (Sept. 29, 2:43 p.m.): Because of an editing error, a previous version of this article gave the incorrect number for Trump’s approval rating on the evening of Sept. 28. It was 38.8 percent, not 38.1 percent.
