The haul isn't huge by Senate fundraising standards, but it's a very solid cash-on-hand figure for a senator who's likely to face an easy path to reelection. It also came while Durbin wasn't very actively fundraising — he didn't officially decide to seek reelection until early March, after most of the fundraising quarter had passed.

A number of Senate Democrats have posted big fundraising quarters, with eight already announcing hauls of more than $1 million.
