The election of Barack Obama as president presents small businesses with an opportunity for health care reform but an imminent threat on labor issues.

That was the assessment of small-business leaders in Washington, D.C., who congratulated the Democratic candidate on his victory and pledged to work with him to restore the economy’s health.

The National Federation of Independent Business, for example, overwhelmingly supported Republicans in congressional races, but still hopes to advance its agenda despite Obama’s big win and Democratic gains in Congress.

“Fortunately, we don’t think Main Street is either red or blue,” said Dan Danner, NFIB’s executive vice president for public policy. “We’re just interested in solutions that solve the problems for small-business owners regardless of party.”
