The endless campaign continues.

WASHINGTON – The campaign never ends.

President Obama today is launching a new p.r. campaign to rally popular support behind his push to raise tax rates on the rich – the cornerstone of his plan to avoid the so-called fiscal cliff that is set to wreck the economy Jan. 1.

Obama’s tax-the-rich scheme also is the chief obstacle to a deal with Republicans to stop the fiscal cliff, when massive tax increases hit nearly every American and huge government spending cuts take effect automatically.

Obama will tout his plan by hosting White House events with small business leaders today and with middle-class Americans tomorrow.

He’ll cap the week Friday with a campaign-style tour of a manufacturing business in Pennsylvania.

Obama has vowed to hang tough for his plan to raise taxes on the rich, despite stiff Republican opposition.

“The president has made clear that he will not sign a bill that extends the Bush-era tax cuts for those making more than $250,000. That is a firm position,” declared White House Press Secretary Jay Carney.
