US help plan demystified?

First of all, it’s my speculation only.

1. On Saturday president Bush presented a plan to donate $700 billion dollars to the US market;
2. On Monday US House of Representatives voted down the plan, stock exchange indexes took a deep dive; (some) investors lost a lot of money;
3. On Tuesday president Bush presented another “refined” plan;
4. On Wednesday the House of Representatives US senate backed the plan;
5. Stock indexes will go up (at least for a moment), investors will need to rebuild their wallets;

My question is why president Bush presented 2 plans?! Doesn’t he have his people in the House of Representatives, who should tell him: “Look George, make it better or we turn it down!”. 

I think it may have been well planned by someone, who knew the first plan would be rejected. Sell shares before Monday, buy them on Tuesday, and you just got richer. I am asking this, because it is not clear. And if nobody knows what something is all about, it is probably about money.

PS) I’ve just realized it hasn’t been backed by House of Representatives yet. But let’s wait till Friday.

PPS) As supposed House of Representatives backed the plan on Friday. Anyone surprised?
