Democratic Rep. Lynch Bucks Anti-Incumbent Trend

U.S. Rep. Stephen Lynch of Massachusetts has survived the anti-incumbent wave.

The four-term congressman from South Boston won the Democratic primary Tuesday against political upstart Mac D'Alessandro of Milton.

Lynch will face Republican Vernon Harrison in November. Harrison, a computer industry technician from Braintree who also works as a stand-up comedian, defeated combat photographer Keith Lepor in the Republican primary.

The 40-year-old D'Alessandro most recently worked as regional political director for the Service Employees International Union. Lynch had lost some labor support even before he broke ranks by voting against the Obama administration's health care overhaul.

Lynch argued he switched his vote because the legislation lacked a public option and retained antitrust protections for the insurance industry.
