Mr. Van Hollen says those grass-roots contributions - that is, small-dollar donors who give, say, $50 or $100 online or in response to direct-mail solicitations - account for about a third of what the Democratic Congressional Campaign Committee raises, with another third from big-dollar donors and the last third coming from the dues paid by members of the House Democratic Caucus.
Overall, as of the end of May, the committee, with $47.2 million, was enjoying a sevenfold cash-on-hand advantage over its GOP counterpart ($6.7 million). "Obviously, the Republicans have had a really hard time," said Mr. Van Hollen, trying to disguise his glee.
But the third-term congressman cautioned that a lot of outside, independent expenditures - much of it generated by conservative groups like Freedom Watch - will supplement the Republicans' resources. "They have become the substitute for the NRCC," he said of such groups.
