Chait believes that Republicans are demographically-impaired. Sean Trende rebuts him:
Ultimately, coalitions are like water balloons. You push on one side, and the other side pops up. In Arizona, Brewer took steps that alienated Latinos (though she still won 28% percent of Latinos), and it cost her. But the Democrats’ stance alienated white voters. I think Chait would say that demographics still doom the GOP in the long run, but if the GOP is winning around 60 percent of the white vote, as opposed to the 50 percent it tended to win for Congress in the 80s or the 55 percent from the 90s, while still holding one-third of the Latino vote, it is going to take a long time for them to take on permanent minority status.
