Hilary the Parser

I can think of a few possible explanations for the contradictory language we're hearing Hillary Clinton use as we get closer to Iowa:
  1. she hopes to appeal to voters on either side of any particular issue, ie be everything to everyone,
  2. she is moving to the right in preparation for the general election,
  3. her positions are as ambiguous as they seem,
  4. she is being deliberately deceptive.
It's hard for me to fathom that this behavior will win her the Democratic nomination, let alone the general election. Didn't we already go through this in 2000 and 2004? The last thing the country needs is another ambiguous, wishy-washy, flip-flopping Democratic candidate, but Hillary appears to be just such a candidate.
