Democrats have struggled to find effective ways to oppose President Donald Trump, and even some Democratic voters describe the party as weak.

CHICAGO — Texas House Democrats who left their state to prevent Republicans from passing redistricting maps will take part in nationwide “Fight the Trump takeover” protest on Saturday.

But in some of the nation’s biggest Senate races, Democrats are relying on an old strategy of recruiting—and then clearing the field for—long-serving party leaders with whom voters are already familiar.

If those conditions are met, the Texas House Democratic Caucus said Democratic lawmakers will return to the Texas House.

Texas Gov. Greg Abbott on Friday called a second special session to push through a redrawing of congressional maps to secure up to five more Republican seats in the US House.

Senate Democrats are banking on familiar, older figures in at least three critical races next year, bucking the tide of momentum toward fresh candidates from the next generation.

After leaving the state to block the G.O.P. from redrawing the state’s congressional maps, Democratic lawmakers are keeping the pressure on from afar.

Lawmakers are now framing their ability to prevent new maps from passing during one special legislative session as a victory. But Republicans are poised to call another.

Sacramento’s most trusted supplier of voter data was once a cheerleader for nonpartisan redistricting. Now Paul Mitchell is setting the lines for Democrats’ mid-decade gerrymander of California's congressional map.
