WASHINGTON (AP) — The latest Associated Press-GfK poll holds some ominous signs for congressional Democrats going into the November elections.

Overall, people are split between preferring Republicans or Democrats to win control of Congress.

But those most interested in politics are increasingly likely to favor GOP control, while favorable views of the Republican Party have grown.

The March poll also found that congressional approval ratings were stagnant at 16 percent — and 39 percent said their own member of Congress deserves re-election.

Looking to 2016, few potential presidential candidates have made a major impression.

Most Republicans hold a positive view of 2012 vice presidential nominee Paul Ryan and Mike Huckabee, a former Arkansas governor.

Democrats are most positive about Hillary Rodham Clinton and Vice President Joe Biden.
