The latest report from CFI.  I consider these CFI reports essential reading for anyone who wants to keep up with campaign financing in the presidential election.  A snippet:

In June, the Romney campaign raised $9.9 million in unitemized contributions of $200 or less. The campaign’s staff had reported a surge in small contributions at the end of the month, after the Supreme Court upheld the Affordable Care Act on June 28. The monthly haul more than doubled Romney’s unitemized contributions of $4.1 million in May, which in turn nearly doubled its $2.4 million in April. The June figure represented 29% of the Romney campaign’s $33.8 million in receipts for the month (up from 17.4% in May and 20.3% in April).

Even so, President Obama’s raised nearly twice as much in unitemized contributions as Gov. Romney in June – $18.6 million to $9.9 million. These figures include unitemized contributions transferred to the campaigns by the candidates’ joint fundraising committees. They therefore are higher than ones reported in some early press accounts. They also were slightly higher than the Obama campaign’s combined $15.1 million in unitemized contributions in May and $11.2 million in April. Unitemized contributions made up 38% of the Obama campaign’s $49.2 million in receipts for June.
