May 18, 2006 — President Bush is hoping for an election-year boost from a $70-billion tax cut package he signed yesterday. The measure extends a pair of tax breaks - one benefiting investors, the other upper-middle-income families. Democrats contend the tax breaks are another gift to the rich that only plunges the nation deeper in debt. President Bush's approval ratings are the lowest of his presidency, and congressional re-election campaigns are getting underway. The tax cuts are seen as one way the president can galvanize his and the GOP's core supporters. Commentator Paul Hetzler wonders how a significant chunk of that political base can go along.
