I was using it in the context of the bill that was passed in 2000 (?) limiting the use of soft money in elections; proliferated money that is given to parties to support getting people to vote. This move was very economically straining, as Conservatives, on an economic basis, prefer free reign with money, for as it turned out, the money would make it to parties, and then their way to candidates, even though it is not money meant to be used in that way. Democrats prefer more restrictions (generally).
In regards to people being Centrist or Moderates, it doesn't totally matter so much. The American Party system is so massively decentralized, that anyone claiming to be anything can vote for anyone else (with the exception of in Closed Primary states). For example, the Southern Democrats, Reagan Democrats, and New England Democrats all have very different agendas, if not completely contradictory. Another example, Ron Paul, who is Libertarian (social liberties above all), is considered Republican because of his belief in economic freedom from big government. De-centralized? Ohh, yes!
Yeah, we know. They killed us in 2000. They are called the Green Party.
