Tax cuts instead of public transportation in Obama's stimulus package

Just days after his inauguration it seems we will see the first letdown from President Barack Obama. In the stimulus package, proposed by Obama, which is designed to ease the financial crisis only 18% of the money will go to infrastructure, such as public transportation systems and a more modern and energy efficient electrical grid.

It seems that Obama in a foolish effort to please the Republicans have agreed to allow over 30% of the stimulus package to go towards pointless tax cuts. Democrat Peter DeFazio, of Oregon's 4th Congressional District, interviewed by Rachel Maddow puts the blame on the Republicans and Lawrence Summers, Obama's own adviser:

I really don't understand this. Why would Obama want to try to please Republicans and their failed policies and ideology? They lost the election and have no real political power left. The people in USA voted for change, not for the same failed policies that have plagued USA and the world for eight years now.
