The political struggle here will be between Obama's desire to present these measures as separate ideas, against the Republican desire to lump them together under the rubric of "stimulus." The endgame will involve a debate over the Republican Party's decision to block Obama's plan. How that plan is defined -- middle class tax cuts, infrastructure, re-training, or simply "stimulus" -- will determine who wins that debate.
I agree, so I think a better speech would propose middle class tax cuts, more middle class cuts and still more middle class tax cuts (plus maybe tax increases for rich people). To be clear not just the whimpy little payroll tax holiday extension but also bringing back the $800 a family Obama tax cut and uh something else. But all taxes so it is simple enough for people to understand.
