Two U.S. senators in jeopardy on big day of voting

Two U.S. senators in jeopardy on big day of voting 18 May 2010 With voter anger running high, two veteran U.S. senators face potential career-ending challenges on Tuesday in primary contests that could measure the anti-Washington mood before November's midterm elections. Democrats Arlen Specter of Pennsylvania and [corporate-owned] Blanche Lincoln of Arkansas face strong tests from the left. Also, a U.S. Senate race in Kentucky between a Republican establishment favorite and a conservative "Tea Party" activist will test the strength of that loosely organized movement.
