A paragraph from the link helps explain why the Romney campaign has been so quiet. (at least in Ma.)
Most of the money that Mr. Romney has raised in the last several months can be used only in the general election, which begins after the party’s national convention this summer, the sources said. The long and contentious Republican primary drained Mr. Romney of much of the money he could spend before then.
That has left Mr. Romney somewhat short of cash, though the campaign is broadcasting advertisements this week slamming Mr. Obama for misleading attacks.
