The Pew Research Center study divides the electorate into nine groups — four Republican, four Democratic and a disparate and disaffected group that does not fit well into either party’s coalition.

Republicans are divided over former president Donald Trump, who continues to dominate as the public face of his party 10 months after leaving office. Members of all GOP groups heavily backed Trump in 2020, but they part ways on his future role. Majorities in just two of the four GOP groups — albeit the largest ones — want him to run again in 2024, and only one of the four groups rates him as the best president of the past 40 years. For two other Republican groups, that accolade goes to former president Ronald Reagan, while the fourth group is divided between Reagan and Trump…

Republicans and Democrats differ on the size and scope of government, a long-standing gulf between the parties. Democrats collectively favor more and bigger government but are divided among themselves on whether services should be “greatly” expanded, with a clear majority of the most progressive group in the party saying yes compared with about one-third of the other Democratic groups agreeing.

Republicans, too, are divided on aspects of economic policy. While most Republican groups are consistently conservative on fiscal issues, one with a more populist bent dissents on the issue of corporate power, saying “business corporations make too much profit” and favoring higher taxes on those with household incomes above $400,000. This puts them closer to many Democrats than to most in their own party.
