By appealing to white voters and characterizing Democrats as the party of the non-white, Republicans can hold onto the House. But the more they’re perceived to be the party of white people, the harder it is for them to win presidential elections. As we’ve seen time and again over the last couple of years, even when national Republican leaders would like to make the party friendlier to minorities, right now the GOP is defined by the one place where it holds power: the House.
One answer to the question of what the Democrats can do to make taking back the House a possibility is simple: They can wait. The demographic groups that make up their coalition are increasing in size as a proportion of the population, while the group that makes up almost the entirety of the GOP’s base is shrinking. It’s a slow process, but as whites become a smaller and smaller portion of the American populace, it’ll be tougher and tougher for Republicans to maintain their lock on the House. They may have it for a while yet. But it won’t last forever.
