Obama heading to Michigan to push taxes on rich

The president's message in Michigan will be that the economy is rebounding and Congress should not risk that progress to save tax cuts for the rich. The president will use the Daimler Detroit Diesel plant where he'll speak to illustrate his point, noting that the company plans to spend an additional $100 million to boost production in the U.S.

The president's re-election campaign also emailed supporters Monday, asking them to call their representatives and urge them to back Obama's fiscal cliff plan, even suggesting a script they could read. It's the latest example of the White House trying to put its massive voter database to use during the fiscal cliff negotiations in the same way it did during the presidential campaign.

Obama's plan would raise $1.6 trillion in revenue over 10 years, partly by letting decade-old tax cuts on the country's highest earners expire at the end of the year. He would continue those Bush-era tax cuts for everyone except individuals earning more than $200,000 and couples making more than $250,000. The highest rates on top-paid Americans would rise from 33 percent and 35 percent to 36 percent and 39.6 percent, respectively.

Boehner has offered $800 billion in new revenues to be raised by reducing or eliminating unspecified tax breaks on upper-income earners. The Republican plan also would cut spending by $1.4 trillion, including by trimming annual increases in Social Security payments and raising the eligibility age for Medicare from 65 to 67.
