Democrats may lose gerrymander gamble

Amid all the ominous political news of this season, Democrats have kept their eyes fixed on a ray of hope: States were redrawing the lines that define congressional districts, and Democrats were making out well in the process.

"How Democrats are winning congressional redistricting fights" was a CNN.com headline last month.

"Republicans built on their existing gerrymanders to try to expand their House advantage," reports Vox, "but Democrats fired back even more powerfully with gerrymanders of their own."

But gerrymandering isn't going to save the Democrats. Not this year, and probably not this decade. It may not even do much to help them.

In part, that's because the new lines aren't final. In Florida, Republican governor Ron DeSantis has persuaded the state Senate to revise the borders in a special legislative session. If his new map prevails, the state will have four more Republican-leaning House seats than it does now.

But there are also trade-offs in redistricting that pose an especially acute problem for Democrats just now. Their voters have become more geographically concentrated over time; they've shed rural voters while gaining city-dwellers. As a result, to maximize the number of House seats they can contest, they have to divide the voters in their urban strongholds among districts. And because the 2020 election left them with full control over redistricting in relatively few places, they have to use this tactic very aggressively where they can.

Nevada is a case in point. Three of the state's four existing House districts tilt Republican. The Democrats, who control the governorship and both houses of the legislature, took Democratic voters out of the district centered in Las Vegas and split them among two other seats. The result was a new map with three districts whose voters went for Joe Biden in 2020.

That's a real prospect in a state with a lot of working-class Hispanic voters, a group that has been moving toward the Republicans lately.

Keep in mind, too, that this wave would be measured against the parties' showing in the 2020 presidential race. On average, Biden ran ahead of Democratic congressional candidates that year, winning over some voters who often back Republicans but couldn't abide former President Donald Trump. Democrats can't count on those voters in 2022.

Republicans have generally followed a different strategy in redistricting. With more district lines under their control, Republicans could afford to make it a higher priority to protect the seats where they already had an advantage. They weren't as aggressive about maximizing the number of seats they could contest. That's why news coverage has played up Democrats' surprising gains from redistricting.

But Republicans got both a short-term and a long-term benefit from their approach. This year, they can concentrate their efforts on a smaller number of winnable seats. And in future elections of this decade, when there might be a Democratic wave, more Republican seats will be safe.

On April 20, the election-watchers at the Cook Political Report revised their ratings of eight House races. Each revision favored the Republicans. The two Nevada seats that got additional Democratic voters through redistricting had been judged to lean toward the Democrats. Now they're "toss ups." Titus' seat, which had not even been considered competitive in 2020, is now rated "lean Democratic."
