Gillibrand on Top

In light of John Sweeney's boasting over appropriations. I have to ask, since Gillibrand can out fundraise the incumbent, doesn't it stand to reason that she'll also deliver more to the district then he has once she's elected?

Swing State Project says:

Gillibrand is on fire. She came close to matching Sweeney's 1Q fundraising, and now she's taking the lead. That's fantastic for a first-time challenger against an established incumbent.
