It looks like Barack Obama has launched his re-election campaign. In a speech to Congress, he unveiled the American Jobs Act, and in effect dared Republicans not to pass it.

The bill reaches out to Republicans on many points. Much of it consists of tax cuts, with a $240bn expansion of the cut in payroll taxes promised, as well as a tax holiday for smaller businesses hiring new employees. He also said that Medicare spending needed to be cut. The bill also retains some spending commitments, such as $140bn for modernising schools and repairing roads and bridges.

In his speech, Obama eschewed the soaring rhetoric for which he is famed, instead urging Congress to "pass this jobs plan right away". Initial responses from Republican leaders imply that they are receptive, although it is unlikely they will pass it in its entirety.

With the lowest approval ratings of his presidency, currently floundering in the 40s, Obama faces the dual challenge of shaking off the public perception that he has failed to deliver on the economy, and the intransigence of the Republican-controlled House.

Tactically, this speech adopted a clever position. Obama's own approval ratings may be dipping, but an incredible 82 per cent of the US public think that Congress is doing a bad job. This suggests that the cynical politicking seen during the debt ceiling crisis did not go unnoticed.

Over at the Huffington Post, Howard Fineman suggests that the speech will set the tone for Obama's re-election campaign:

By putting forward a simply-named, to-the-point bill -- the American Jobs Act -- and by challenging Congress to pass it and pass it now, Obama hopes to create a win-win: either the Congress accedes or, as President Truman did in 1948, he can run against the "do nothing" Congress.

This strategy has the potential to be effective, given public frustration with politics in general. With some comments bordering on sarcasm, he presented the debate as a conflict between the majority of voters, and those who believe that "the only thing we can do restore prosperity is just dismantle government, refund everyone's money, let everyone write their own rules, and tell everyone they're on their own."

But the relentlessly confrontational stance that Republicans have so far adopted is not Obama's only problem: there is also the jobs question itself. Analysts predict that the plan, if passed, will encourage growth, but unemployment remains stuck at 9.1 per cent and it is unlikely that this bill -- however well-intentioned -- will substantially change that. However, after weeks of what many viewed as a frustrating lack of action, it is good to see Obama get off the back foot and go in fighting.
