"Tim Grace" asks:
Does the SCOTUS campaign finance rulling open the door for single-issue driven third party/independent candidates?
Tim also asks whether Scott Brown drove the truck down to DC; the answer is no, but he did wear the barn jacket. Don't know whether John Kerry wore his from the 2004 campaign when they met up.
As for yesterday's Supreme Court ruling on campaign-finance reform, I still haven't had time to really analyze the ramifications, so I'll have much more to say at some future point. My initial thought is that it could, in some individual cases, benefit the kind of candidate you're talking about, but I expect in most cases it will benefit the major-party candidates who typically receive the bulk of corporate and labor backing.
