Marx said that every class struggle is a political struggle. This means that, if the proletarians and capitalists are waging an economic struggle against each other today, they will be compelled to wage a political struggle tomorrow and thus protect their respective class interests in a struggle that bears two forms. The capitalists have their particular business interests. And it is to protect these interests that their economic organisations exist. But in addition to their particular business interests, they also have common class interests, namely, to strengthen capitalism. And it is to protect these common interests that they must wage a political struggle and need a political party.

It’s also a bit.
