OK, quick US legislative process 101...
The President has decided that all schools should be painted orange.
His staff write the bill.
It's presented to both houses of Congress
It then goes to the education (painting buildings subcommittee) committees.
They approve the bill, but disagree with the Pres' choice of orange, and insist that the bill is amended to allow for any shade of orange.
Congressman Puck from Buttfuck my Sister, Tennessee has a paint factory in his district and wants to ensure that they get a slice of this juicy federal contract, so makes a speech in the house, but essentially aimed at the ways&means committee (who decide WHERE the money will be spent) and Pres that this company are a swell bunch of guys and that they are developing an orange paint that reacts with sunlight to change colour through the day which would thus save the Fed loads of money buying lots of different shades of orange.
Several other Congressmen in both houses make similar requests/amendments.
The amended bill then goes back to the White House for the pres approval...unfortunately he doesn't like Sen Puck so strikes his request for funding from the bill. It then goes back to Congress.
By this time, Sen Puck has managed to get a llittle caucus of supporters, all of whom have companies with colour-changing paint in development. They make up enough of a group to kill the bill, so re-insert an amended amendment calling for even more money for research into these magic paints.
Pres realises his keynote bill will fail unless he compromises, so basically buys off enough of the bods in Sen Pucks caucus to get it through.
Both houses pass the bill
Pres is happy, and signs off on it
Bill becomes law.
The Ralph Nader School for pains in the ass object to having their school painted Orange, and sue under the First Amendment that a law saying what colour schools have to be is an infringement of civil rights.
Their local, district, regional and State courts pass it along to the Supreme Court who rule that, yes, the Federal Govt has no right to tell schools what colour to paint themselves.
And that, ladies and gents, is how a Bill is passed in the US...
