Repetition, repetition, repetition. In trying to discern Obama's intentions and strategy regarding long term tax/budget reform, I have referred repeatedly (

Beyond Ideology: Politics, Principles and Parisanship in the U.S. Senate by thorough statistical analysis of roll-call votes from 1981--2004, one caveat is in order. Tax policy is already so polarized by party that there's not that much room for a President to worsen the division:
Presidential involvement has little influence on partisanship on votes dealing with social issues and the distribution of the tax burden...These are clearly party-defining issues regardless of whether a president demands action on them. Generally speaking, taxes and abortion sparked partisan division in the Senate at approximately the same levels regardless of their presidential agenda status (p. 83).
According to Lee's tabulations, party division on Senate roll call votes from 1981-2004 concerning distribution of the tax burden was 66 overall, and 71 on tax legislation in which "presidential leadership" was exerted. That's in contrast to nonideological issues, where party differences are relatively small
until a president advocates a specific policy, at which point the parties usually divide. Partisan division on votes concerning space, science and technology, for example, averages 30.5 points higher on votes over legislation on which the president has exerted leadership than on votes on which he has not.
One might conclude that in the pre-polarized tax/spending arena, the president has little to lose by drawing the battle lines clearly and fighting it out in the arena of public opinion. Why shouldn't Obama lay out a tax/deficit plan somewhere left of the Bowles-Simpson plan and throw his energy into hammering the devastation to be wrought by the GOP's wholly unnecessary cuts to discretionary domestic spending -- and to the decimation of Medicare and Social Security required by the "no new taxes" pledge that over 90% of Congressional Republicans have signed? What's he got to lose?
