KANSAS CITY (AP) -- Barack Obama is still out on the road, renewing his emphasis on economic themes.
Obama is pledging to enforce occupational safety and health regulations as president. And he's declaring that John McCain "doesn't get it" when it comes to the anxieties that many middle-class workers are facing.
Obama is making his way through a handful of battleground states before arriving in Denver to accept his party's presidential nomination.
In Missouri today, Obama spoke to workers at a giant hangar where American Airlines planes are serviced. The plant employed 3,500 people in 2001, but the work force has since been cut to about 1,000.
Obama criticized what he called the Bush administration's lax enforcement of OSHA rules, and pledged to strengthen them.
Obama has kept a relatively light public schedule this week, not wishing to distract from the carefully scripted program unfolding in Denver.
