New York Sen. Hillary Clinton is in Northern California on a fundraising trip.

The guests were seen pulling up to an estate in Sacramento, owned by a developer who has been a large Democratic contributor in the past.

Whether the senator is raising money to run for president is anybody's guess.

These days, running for office is so expensive, fundraising is an ongoing endeavor.

That may be why Clinton was also the honored guest at a second fundraiser in San Francisco Thursday night.
