Well, the truth is: it is very important! But at the same time, it is also pretty unimportant!
The promise of Big Money to help a candidate for high office win his next election is hard to resist. The threat of Big Money to hurt a candidate’s chances to win his next election is also hard to resist. Indeed, even more important than impacting election outcomes is the power that Big Money purchases to influence – or even write – legislation that favors its own interests. Even if YOUR candidate refuses Big Money, enough other legislators will go along with Big Money’s demands that it won’t matter if YOUR guy is incorruptible.
But how can it be true at the same time that Big Money is not really important?
