The House and the Senate, of course, are elected independently. They have no obligation to do anything a president suggests. Furthermore, the Constitution squarely puts responsibility for the federal budget in the House of Representatives. All appropriations and tax bills must originate there. Appropriations and taxes, of course, are the federal budget.
Presidents can only recommend a budget.
Presidents can veto appropriations and tax bills, but the legislative branch has the power to override his vetoes. It is unlikely that Congress will pass the president's budget, including his proposed tax cuts, as he presented it. He will, however, likely get most of what he has recommended. At that point, voters will see another characteristic of Bush. He will not r eact to legislative defeat with bitterness, name-calling and recriminations.
