More good news for Libertarian Party prospects.

Americans who self-identify as politically independent hit a 25-year high of 46 percent in the fourth quarter of 2013, according to a new Gallup poll. The poll did not ask participants if they identified specifically as Libertarian.

For all polls conducted during 2013, the average percentage of respondents who identified as independent was 42 percent, another high mark since Gallup started conducting the poll 25 years ago.

The Gallup poll findings corroborate with other recent polls that show declining approval ratings for Democrats and Republicans and a rise in the percentage of Americans who self-identify as, or lean, libertarian.
