The Wall Street Journal's Neil King sets up unemployment as a leading issue in the 2010 midterm election, quoting Democratic pollster Peter Hart as saying "Anytime unemployment hits double digits, it's hard to see the party in control having a good election year." Unemployment is now nearing that double digit mark, hitting 9.8% in September.

The Obama administration, for its part, is now pushing--again--a tax credit for companies designed to decrease unemployment. Catherine Rampall of the New York Times reports that the tax credit idea is gaining traction among both parties, and details are coming soon: One version of the approach, to be unveiled next week by the Economic Policy Institute , a labor-oriented research organization, would give employers a two-year tax credit if they increased the size of their work force or added significant hours of work (for example, making a part-time worker full time). Employers would receive a credit worth twice the first-year payroll tax for each new hire, amounting to several thousand dollars, depending on the new worker’s salary. “It’s beautiful if it can be timed at a dire moment like this, when unemployment is way too high and appears to be going somewhat higher,” said Mr. Phelps, an economics professor at Columbia, lamenting that the president dropped it from the $787 billion stimulus plan approved in February. “But it’s a pity that this wasn’t done a year ago.” One of a number of ideas being discussed, the policy is intended to encourage companies to start hiring again by making it cheaper to add new workers. It has raised concerns, though, that employers might try to exploit the system. Read Support Is Building for a Tax Credit to Help Hiring here.
