In the bubble during the Obama years, around 2010-14 or so, they openly talked about how it would take "30+ years in the political wilderness" for the GOP to win another national election. They would have to learn to be more liberal, to basically become "Democrat Lite," before anyone would ever vote for them again, because the entire country had swung hard to the "center" (i.e., the left, since they consider the DNC to be a conservative party) and thus the GOP wasn't electable anymore.
They could keep some of the southern states, for now, because everyone knows Southerners are stupid rednecks who vote against their own interests (namely, having liberal coastal elites rule over them). But their states would be "saved" as the Latinos out-breed the native southerners (read: whites), and who cares, the SCOTUS will fix any laws in red states that are too red -- like forcing them to accept baby killing and degeneracy.
This was not only a standard talking point, it was damn near a lefty hymnal. They genuinely believed in the eternal DNC majority. They literally couldn't grasp the concept of people disagreeing with them. The only way the GOP could win elections was by cheating.
