Sen. Susan Collins (R-Maine) barely outraised Rep. Tom Allen (D-Maine) 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 $6.58 million this cycle and had more than $5.13 million on hand.

Meanwhile, Allen’s campaign reported raising just over $1 million in those three months. Allen had $3.13 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.
