A Democratic challenger to U.S. Rep. Don Young says he plans to file his candidate paperwork Wednesday with the Alaska Division of Elections.

Matt Moore, a former legislative candidate with a medical consulting business, is among five people running against the Alaska Republican. Moore lives in Anchorage.

Beside Moore, three other Democrats seek that party's nomination to challenge Young. They are state Rep. Sharon Cissna of Anchorage and little-known Democratic candidates Doug Urquidi of Eagle River and Frank Vondersaar of Homer.

The other challengers are Republican John R. Cox of Anchor Point and Libertarian Jim McDermott of Fairbanks.
