I don’t know what exactly the middle is. I do know independents, the non-affiliated, the less to non-partisan group has grown from 30% in 2006 up to 43% today. But they’re a mixed bag. Most independents support the republicans on some things, issues and the democrats on other things, issues. Very few are smack dab in the middle ideological wise. I like to use the example of someone being pro-life and pro-2nd amendment at the same time. But with both major parties looking for ideological purity, that person doesn’t pass either major party’s litmus tests.
Even with both major parties shrinking, there will be no viable third party to challenge them. Republicans and democrats write our election laws and they do so as a mutual protection act. Then there’s the financial aspect with all these billionaires, lobbyist, corporations, etc. giving their money to both major parties in the tens or hundreds of millions of dollars with nothing to any of the third-party kind. You can’t blame them, they want a good return on their investment, er, donations which no third party or independent can provide.
On the presidential level alone, Harris raised and spent almost 2 billion dollars to Trump’s 1.45 billion with little poor Jill Stein in third place at 2.7 million.

Almost 16 billion dollars were raised and spent by the two major parties in all the 2024 election races.

There’s no competing against both the elections laws which discourage all independents and third party candidate along with all the money.
