How To Stimulate the Economy?

TW: There is much discussion of how to best address the economic crisis that is rapidly evolving from a primarly finanical market problem to a "real" economy consumer driven deep recession. The attached chart from Moody's speaks to how various policy options most effectively stimulate the economy. The Republicans love to talk up tax cuts but Keynesian spending appear to have a more effective result.

The problem comes reconciling any policy changes with the realities of politics. Ideally any stimulus should be temporary, the reality is if a tax is "cut" then to reverse the "cut" one must "increase" taxes leaving the increasing party (the Dems) vulnerable to the Republicans crying socialism etc. Correspondingly if fiscal stimulus is applied (e.g. more spending) the Dems will weep and moan when the spending is pulled back in. The answer would be responsible political leadership, a challenging goal.
