I think perhaps a more accurate way to pose the question would be:
"will the party remain detached enough from the opinions of rank & file democrats, that they they'll lose votes to the other side or cause their own people to stay home?"
There's a few different datapoints one can look at:
Per pew research (pertaining to party identification - which doesn't always line up with registration):
- Direct party identification:
- 33% identify as Democrats
- 32% identify as Republicans
- Independents or other affiliations: 35%
- Among these, 16% lean toward the Democratic Party, and 15% lean toward the Republican Party.
And per official voter registration tallies (across 31 states and DC) in the United States is as follows:
Party | Registered Voters | Percentage |
---|
Democratic | 46,121,872 | 37.6% |
Republican | 36,556,705 | 29.8% |
Unaffiliated/Independent | 34,006,350 | 27.7% |
Other | 5,892,367 | 4.8% |
According to exit polls, roughly 4-5% of self-identified democrats (which equates to just shy of 2 million people) voted for Trump in 2024.
Technically speaking every affiliation is a "minority" in that none have a Condorcet majority, and in order to win in a "2 team head-to-head battle", all would need to rely on at least some votes from one of the other 3 categories to get past the finish line.
Registered republicans are more of a minority than registered democrats at the moment.
I don't necessarily think that America is necessarily getting more conservative, I think it's more of a case where the Democratic party has moved to left on social issues at a quicker rate than a large chunk of the country (especially among independents)
Today's republicans & independents are more liberal on many of the social issues than Democrats from the late 90's.
Same pattern exists for attitudes about marijuana legalization, and we've seen numerous red states pass their own pro-pot and pro-abortion laws at a state level.
Here's the data point to note:
The Median 1994 democrat is closer to the Median 2017 republican than they are to the Median 2017 democrats
That's why independents are the key to winning elections in the US. And further (and faster) you move, the more you run the risk of leaving some people behind via ending up further away from them than the other party, and the more you need to appeal to independents to backfill those votes.
I think a 2012 Democrat would have beaten a 2024 Donald Trump.
