Sen. Susan Collins (R) barely outraised Rep. Tom Allen (D) in the second quarter of the year, according to their respective campaigns.

Collins has outraised Allen in every single quarter of their race so far, but this is the smallest margin — a difference of about $56,000 — to date.

Collins raised $1.06 million in the financial reporting period from April 1 to June 30. The Collins campaign reports it had raised $6.6 million this cycle and had more than $5.1million on hand.

Meanwhile, Allen’s campaign reported raising just more than $1 million in those three months. Allen had $3.1 million in cash on hand.

Though Maine has voted mostly for Democrats statewide in the past few cycles, Collins has had double-digit leads over Allen in many public opinion polls.
