Primaries see late scrambles, even on 'Obamacare'

By

ATLANTA (AP) — Republicans around the country are pleading with voters to turn out in high-profile Senate races on a busy primary day.

And a top Democratic Senate hopeful has her own scrambling to do, as she juggles the political realities of President Barack Obama's health care overhaul in a Republican-leaning state.

Georgia's Michelle Nunn said in an interview leading up to Tuesday's primary that she couldn't say how she would have voted on the Affordable Care Act in 2010.

She'll certainly hear about that answer once Republicans settle a seven-way battle. The GOP primary Tuesday is expected to lead to a two-candidate runoff.

Elsewhere, Senate Minority Leader Mitch McConnell is expected to advance in Kentucky, setting up a tough general election.

There are also primaries in Arkansas, Idaho, Oregon and Pennsylvania.
