New Clinton ad questions Obama lock

WASHINGTON, May 16 (UPI) -- Democratic presidential hopeful Hillary Clinton is airing ads in Kentucky and Oregon, with one ad challenging the notion that she is all but out of the race.

The Kentucky ads focus on the New York senator as a champion of blue-collar voters, The Hill reported. The Oregon commercial challenges political pundits who have declared Sen. Barack Obama of Illinois the almost certain winner of the race for the Democratic nomination.

Clinton has said she will continue to campaign at least through June 3, when the primary season wraps up with Montana and South Dakota. Kentucky and Oregon hold their primaries next Tuesday.

One Kentucky ad, with the title "Right Track," shows Clinton calling for higher taxes for hedge fund and private equity managers. The other, "Partner," features people talking about their financial problems.

In the Oregon ad, an announcer takes on TV pundits Tim Russert and George Stephanopoulos for effectively declaring Obama the Democratic nominee.
