CHARLOTTE, N.C. (AP) — First lady Michelle Obama lovingly praised her husband Tuesday night in a prime-time Democratic Convention speech as a devoted husband and caring father at home and a "man we can trust" to revive the nation's weak economy as president, beckoning the country to return him to the White House despite agonizingly slow recovery from recession. "He reminds me that we are playing a long game here ... and that change is hard, and change is slow and it never happens all at once," she told a nation impatient with slow economic progress and persistently high unemployment of 8.3 percent. "But eventually, we get there, we always do," she said in a speech that blended scenes from 23 years of marriages with the Obamas' time in the White House.
