Based upon your needs... I would diversify a bit.
I would keep SOME of your money in cash. I know that Obama MAY start aggressively printing money down the road... so it DOES have some risk... BUT it offers you liquidity... AND Gold EVENTUALLY WILL go back down to below $400.00 an oz. I can predict that with pretty good certainty.... but it MAY happen after Obama is long gone.
Also holding cash actually will sabotage Obama FAR MORE than buying gold. Since if you buy gold... the gold dealer may take your money and just put it back in the bank.. or stocks, etc. If you keep some of it in cash... you can add to deflationary pressure.... but again... there is that risk that Obama may let the printing presses run... out of desperation/frustration.... but that wouldnt be for a while.
Also... for diversification... you may consider silver. its at about $11 an oz, but just like gold it DOES have the potent to half its value.
I would also consider temporarily investing in China until after Obama leaves.... and then removing it later. Investing in China can have a VERY damaging effect, because it can increase the trade deficit, reduce the value of the dollar, and increase the likelihood of bankruptcy. China WILL be negatively effected by the recession.. BUT it WILL have the best opportunity to protect itself since it has HUGE reserves, and virtually no debt. something like PGJ is a safe way to do that.
