Establishment vs. outsiders in Tuesday's primaries

WASHINGTON (AP) - It's the political establishment vs. the outsiders in Tuesday's primaries.

And the establishment has the better odds.

Republican Sen. John McCain and Sen. Lisa Murkowski are poised to win bitter primaries in Arizona and Alaska against tea-party-backed candidates.

In Arizona, former Rep. J.D. Hayworth hoped anti-incumbent sentiment would help him return to Washington.

The radio host's challenge to McCain appeared to fall flat, though.

One poll last month showed McCain, the 2008 Republican presidential candidate, with a lead of as much as 45 percentage points.

McCain's former running mate, former Alaska Gov. Sarah Palin, tried to help a tea-party-backed candidate in Alaska.

But newcomer Joe Miller is not expected to upset the popular Murkowski.
