They aren't ineffective so much as the thing they are attempting to do is not what they say.
The democratic party is controlled opposition. Democrats, like Republicans, take in a ton of money from the donor class.
America is a capitalist nation, in capitalism, those with the capital get to reap the profits. The people with the capital therefore end up with more money, and they can use that money to donate to the political class. This causes the political class to become an instrument of the capital class, and the parties end up being marketing.
The goals of the democratic and republican parties both end up to serve capital. Republicans have an easier time since they have incorporated serving capital into their political platform. Democrats end up seeming ineffective because their messaging is that they are somehow taking most of their money from the capital class but are actually on the side of the labor class.
The capital class has the money, but the labor class has the numbers, both parties need the numbers because until we completely do away with democracy, people, not dollars, get to vote.
As the democratic party has become more and more captured by the capital class and their donations, they can no longer seek votes through advancing policies that would support the labor class by restraining the capital class (this would make their donors unhappy). The democratic party pivoted to trying to find a way to carve out least-bad pro-capital class reforms (things like public-private partnerships, school vouchers, etc), least-disruptive pro-labor class reforms (entrenching capital class insurance companies as some kind of improvement to healthcare, slow rolling minimum wage so they could have symbolic victories for keeping up with inflation, and then not even doing that), and more and more towards cultural issues that do not threaten the capital class (LGBTQ+ rights, DEI, etc).
Republicans have adopted populism and wedge issues politics to capture the labor class vote.
The reason the democrats are terrible opposition isn't because we've somehow elected the dumbest people imaginable, it's that they are pointing at a different goal. Their goal is to remain in the political class, to keep the donations of the donor class (which just happens to be the capital class) flowing, and if that class says "let the massive tax cuts for us play out, we don't care about the fallout" that's what they will do.
