"Now that the race [is] a two-person contest, Mr. Romney ought to be able to bring more small donors in," said Michael J. Malbin, executive director of the Campaign Finance Institute (CFI), a Washington-based think tank. "But to do so, some things will have to change. He will have to gain more passionate support or more committed support as opposed to respect. He will have to make a real effort to find these people and go after them. This campaign at several points has said that it was doing so, but we do not see much evidence of that."
