ATLANTA (AP) — Look closely enough at the 2018 midterm campaign and you’ll see the stirrings of a Democratic scramble to reclaim the White House from President Donald Trump.

The leading players — from established national figures such as former Vice President Joe Biden and Sens. Bernie Sanders and Elizabeth Warren to up-and-comers including Sen. Kamala Harris — don’t necessarily put it that way. But the potential 2020 candidates are making the rounds, raising and distributing campaign cash among fellow Democrats, endorsing candidates and meeting political activists.

Their movements reflect competing strategies for establishing their reputations and shaping a party that lacks a clear leader and consistent message in the Trump era.

For senators trying to get better known, a primary goal is proving fundraising strength and party loyalty, without necessarily taking sides in the larger fight between the left and moderates who split on the minimum wage, health insurance and other issues.

“I just want to do whatever I can” to help Democrats win, Harris said at a recent stop in Georgia, where she was campaigning and raising money for Stacey Abrams’ race for governor.

It is part of an aggressive effort for the freshman senator from California. She’s raised $3.5 million for her Senate colleagues and the Democratic Senatorial Campaign Committee, plus what she helps candidates such as Abrams raise directly when she appears with them, and at the end of April Harris had nearly a $1 million balance in the political action committee that she uses to back other Democrats.

Warren boasts that she’s raised $15 million for other Democrats since her 2013 election. The Massachusetts senator faces a re-election campaign this fall, but not as tough a race as confronts 10 colleagues running in states where Trump won. Like Harris, Warren and New Jersey Sen. Cory Booker have aided those senators.

Warren is also helping other branches of the party: a transfer of money to House Democrats’ campaign committee, $5,000 for every state party and $175,000 spread across state legislative campaigns in contested states.

Democratic and Republican campaign veterans say such contributions and fundraising trips aren’t explicitly about future campaigns. “We’re not playing 3D chess,” says Harris spokeswoman Lily Adams, who describes the senator’s priority as “building our numbers in the Senate” for the final two years of Trump’s term, while looking for strong women and minority candidates. (Abrams would be the first female African-American governor in U.S. history.)

Operatives also insist there are no quid pro quos, though Republican presidential campaign veteran Rick Tyler says, “These guys are out there accumulating chits.”

Tyler worked for Texas Sen. Ted Cruz’s 2016 White House campaign. Cruz was among the conservatives who traveled the country before his campaign, endorsing like-minded conservatives and raising money. Trump’s improbable rise obliterated that groundwork, but Tyler said it’s nonetheless a necessary part of a national campaign, because prospective presidents build their networks and test messages as they meet activists and voters beyond their personal bases.

Harris, for example, is noticeably avoiding most early presidential nominating states — no trips to Iowa or New Hampshire so far. Because 10 Senate Democrats must seek re-election in states Trump won, her travels do put her in some of the pivotal states in the battle to control the Senate.
