Harris fundraising edge on Trump alarms Senate Republican leaders

• The slide notes the $10 million the Harris campaign transferred to the Democratic campaign arm last week.

Driving the news: Daines' presentation was "clear-eyed" about the money gaps, according to a source familiar. The message was that if the imbalance isn't made up, Senate leaders would have to make hard decisions about where to allocate their resources.

• The lunch led to a slew of donations from senators, adding up to nearly $7 million, sources familiar with the total told Axios.
• More than half of that came from Sen. John Thune (R-S.D.), who committed a record-breaking $4 million single transfer.
• Thune's contribution comes as the race heats up between him and Sen. John Cornyn (R-Texas) to be the next GOP Senate leader.

What they're saying: When asked about Harris' eye-popping fundraising and transfer down ballot, Thune told Axios, "When you get an infusion like that, particularly ... if they're hard dollars, which go a lot further ... it makes a difference."

• "We're paying attention to that, and I think it just means we've got to intensify our efforts."

The big picture: McConnell has built out a massive fundraising infrastructure that has helped fuel GOP victories in the Senate.

• His successors' ability to carry on that work will be critical.
