Zoom out: Confidence peaked on January 21, after Pres. Trump took office, as Republicans were super-optimistic about the economy's prospects.
Republicans are still broadly optimistic, per the data from Morning Consult. But among Democrats it's "approaching lows observed during the pandemic."
How it works: Morning Consult measures sentiment by asking people questions about both current economic conditions (good or bad?) and their expectations for the future ( better or worse?).
They roll those results up into an index; any number more than 100 is positive.
By the numbers: Confidence fell to 90.6 on the index Monday — down five points from a week ago.
Caveat: This is one data point, and the stock market so far is rallying today.
