Have Republicans decided it's do or die, that if they can't hold on to power now, they'll never win again?

Steven Levitsky and Daniel Ziblatt, Why Republicans Play Dirty, NYTimes, Sept. 20, 2019:

Why is the Republican Party playing dirty? Republican leaders are not driven by an intrinsic or ideological contempt for democracy. They are driven by fear.

Democracy requires that parties know how to lose. Politicians who fail to win elections must be willing to accept defeat, go home, and get ready to play again the next day. This norm of gracious losing is essential to a healthy democracy.

But for parties to accept losing, two conditions must hold. First, they must feel secure that losing today will not bring ruinous consequences; and second, they must believe they have a reasonable chance of winning again in the future. When party leaders fear they cannot win future elections, or that defeat poses an existential threat to themselves or their constituents, the stakes rise. Their time horizons shorten. They throw tomorrow to the wind and seek to win at any cost today. In short, desperation leads politicians to play dirty.

Take German conservatives before World War I. They were haunted by the prospect of extending equal voting rights to the working class. They viewed equal (male) suffrage as a menace not only to their own electoral prospects but also to the survival of the aristocratic order. One Conservative leader called full and equal suffrage an “attack on the laws of civilization.” So German conservatives played dirty, engaging in rampant election manipulation and outright repression in the late 19th and early 20th centuries.

In the United States, Southern Democrats reacted in a similar manner to the Reconstruction-era enfranchisement of African-Americans.

Diversify!

The only way out of this situation is for the Republican Party to become more diverse. A stunning 90 percent of House Republicans are white men, even though white men are a third of the electorate. Only when Republicans can compete seriously for younger, urban and nonwhite voters will their fear of losing — and of a multiracial America — subside.

Such a transformation is less far-fetched than it may appear right now; indeed, the Republican National Committee recommended it in 2013. But parties only change when their strategies bring costly defeat. So Republicans must fail — badly — at the polls.

American democracy faces a Catch-22: Republicans won’t abandon their white identity bunker strategy until they lose, but at the same time that strategy has made them so averse to losing they are willing to bend the rules to avoid this fate. There is no easy exit. Republican leaders must either stand up to their base and broaden their appeal or they must suffer an electoral thrashing so severe that they are compelled to do so.
