Why doesn't Obama stand up to Republicans instead of being so weak and bipartisan?

[Radical Activist]

An excerpt from Obama's speech at a factory providing green energy jobs as a result of the stimulus bill.

Now I’ll be honest with you, there’s going to be a big debate about where we go. There are folks in Washington right now who think we should abandon our efforts to support clean energy. They’ve made the political calculation that it’s better to stand on the sidelines than work as a team to help American businesses and American workers.

So they said no to the small business tax cuts I talked about. They said no to rebuilding infrastructure. And they said no to clean energy projects. They even voted against getting rid of tax breaks for shipping jobs overseas so we could give those tax breaks to companies that are investing right here in Wisconsin.

And my answer to people who have playing politics the past year and a half is, they should come to this plant. They should go to any of the dozen new battery factories, or the new electrical vehicle manufacturers, or the new wind turbine makers, or the solar plants that are popping up all over this country, and they should have to explain why they think these clean energy jobs are better off being made in Germany or China or Spain, instead of right here in the United States.

We've all heard the talking point that Obama needs to stop being so bipartisan and really stick it to Republicans. He did that yesterday. But I couldn't find the above quote in any of the articles I read about the speech.

The fact is that Obama frequently attacks Republicans. He does it very convincingly. These comments are typical of other speeches. We shouldn't be asking why Obama doesn't criticize Republicans more.

We should be asking why the corporate media censors Obama when he does. And why do so many left pundits and bloggers keep playing along?
