WASHINGTON (AP) — Sounding the keynote for his party's national convention, Chris Christie promised that GOP nominee Mitt Romney will lay out for the American people the painful budget cuts it'll take to wrestle the government's debt and deficit woes under control.

The combative New Jersey governor's hopeful words, however, flew into a headwind of reality: In nearly a year of campaigning, Romney has yet to detail how he would do that.

Former senator and presidential candidate Rick Santorum became the latest Republican to stretch the truth in taking President Barack Obama to task over his administration supposedly waiving work requirements in the nation's landmark welfare-to-work law.
