Is Obama's Proposal Any Good? Ctd

Howard Gleckman decodes Obama's latest gambit:

Keep in mind that while Obama’s initiatives seem expansive, their real budget cost is relatively low. Because companies would have deducted this newly-expensed investment over time anyway, they will effectively pay back any short-term tax savings and Treasury will eventually recover most of its revenue loss. The White House claims business would get an immediate tax cut of $200 billion but figures the 10-year cost of this 15-month proposal would be only about $30 billion.

... while the economics is interesting, this proposal is all about politics.
