In addition to the election of Barack Obama, the election of November 4 also marks a significant breakthrough of the Democratic Party in Congress. For the first time since 1995, he returned to the unquestionable and simultaneous control of the White House, the House of representatives and the Senate. "Also the Bush Presidency that would necessarily reduce the Republican contingent, the management of the economy, housing crisis and the financial crisis, has created a strong resentment towards the party," says political scientist Julian Zelizer (Princeton University).
Fateful threshold

Two years after already obtaining a balance in the Congress, after eleven years of Republican rule, the Democratic Party consolidated its position with at least 14 additional seats in the House of representatives, or a total of 251 seats against 173 for the Republicans and 56 seats in the Senate, against 40 for the Republicans. Even if the Democratic Party does not cross the fateful threshold of 60 seats in the Senate that would have provided a total control of the Congress, this result includes administration Obama a comfortable margin of manoeuvre on priority sites such as tax policy and health. "The majority of the 60 seats in the Senate was not crucial for Barack Obama, because it can make its reforms with a clear majority," said political scientist David Epstein (Columbia University). So far, it is only through the rallying of two independent, Joe Lieberman (Connecticut) and Bernie Sanders (Vermont) that the Democratic Party could claim a short majority of 51 seats, against 49 Republicans in the Senate.
The House, where he already had a fair majority with 235 seats (compared to 199 for Republicans so far), the Democratic Party has new seats in New England, Florida, New York, Arizona, and Virginia. At the same time in the Senate, where was involved the renewal of one third of elected officials (on a total of 100 seats, two by federated state), the Democratic Party gets five additional seats in Virginia, North Carolina, New Mexico, New Hampshire and Colorado.
On control of the Senate is all the more valuable to future President that the members of the Congress, which are not their leaders for their re-election, sometimes express their independence from the administration in place. Thus, despite the urgent appeals of George w. Bush and the leaders of the two parties, the House of representatives had rejected, on 30 September, the Wall Street $ 700 billion rescue plan proposed by the Secretary of the Treasury, Henry Paulson, requiring to revise its copy. It is only after reviewing the project by the Senate that Congress finally passed the project revised to 263 votes against 171, October 3.
Legislative building
The first Legislative building which should be facilitated by the democratic breakthrough in Congress include the gradual withdrawal of American troops from the Iraq, but the repeal of the tax cuts of George w. Bush for the most privileged households and the management of the financial crisis. However, the budgetary context may curb the major reforms of education and health as a first step..
