A possible referendum in Oregon on animal rights would end fishing, hunting, even pest control, just when Democrats are trying really hard not to be seen as “weirdos again.”

The lawyer, Dan Cogdell, helped save Mr. Paxton from criminal charges and an impeachment, but now he says the Texas attorney general has “lost sight of his mission.”

We’ve grouped six battleground states by some of the factors that shape how likely it is for the party to flip each Senate seat.

Democrats cheer there is a way, even as new worries emerge over whether Graham Platner can flip a Maine seat. Republicans remain confident they will prevail in Texas, Iowa and Alaska.

Jim Rigby, a pastor who rarely uses the word “God,” is a key to understanding the Senate candidate trying to pull off something unusual in Texas.

After attacking the Texas attorney general, who won the G.O.P. nomination, Senate Republicans are pivoting sharply to support him in what is now a competitive race.

Personal attacks and a packed campaign rally set the tone for what is likely to be a rancorous contest for U.S. Senate between James Talarico and Ken Paxton in Texas.

Ken Paxton’s victory for the Republican nomination and a big shift among Hispanic voters have put a Senate seat within reach.

Many Democrats and some Republicans said the scandal-plagued Ken Paxton’s victory could turn Texas into a battleground state that will determine Senate control.

Republican voters made a familiar bet, that Texas is conservative enough that any Republican, even the most conservative, will beat a Democrat.

James Talarico, the Democratic nominee for U.S. Senate, has been raising money and looking to unite his party for the general election.

President Trump has sought revenge in G.O.P. primaries. Democrats have turned out to vote in large numbers. Republicans have gained a redistricting advantage.

James Talarico, the Democratic nominee from Texas, hopes to counter what he sees as a conservative takeover of the American church.

A carefully disciplined campaign that capitalized on viral media, months of organizing and strong outreach to Latino voters helped propel James Talarico to the center of Texas politics.

After clinching the Democratic Senate primary, he told supporters in Austin that the country’s real divide is between “top versus bottom,” not the left versus right.

After the state representative won the Senate primary, he joined a list of other promising progressives who have captured the left’s fancy.

Talarico’s victory got a lot of attention, but Cornyn’s showing may be the most consequential result.

The veteran Texas senator faces what promises to be a bruising runoff with the state attorney general challenging him from the right. But he had a stronger showing than expected.

At a moment when many Democrats are campaigning on rage and resistance, James Talarico took a different tack in his campaign in the Texas Senate primary.

James Talarico won the state’s Democratic primary for Senate, while Senator John Cornyn faces a runoff against Ken Paxton, his right-wing challenger.

Midterm season is kicking off with hard-fought Senate and House primary contests that include battles over political style and ideology, age and scandal.

The Texas Democratic Senate primary is more about persona than policy, and the same is true for many other races.
