In the wake of John Edwards' withdrawal from the race, Dave Obey today endorsed Barack Obama:

WASHINGTON, D.C. – In response to many questions from private
citizens and members of the Press, Wisconsin Seventh District
Congressman Dave Obey (D-WI) today issued the following statement:

"For eight long years, in extreme partisanship, George W. Bush has
governed this country by dividing it. He has pursued disastrous foreign
and domestic policies and has stubbornly refused to listen to anyone’s
views except those who march in lockstep with him. America desperately
needs a new president who can reach across old barriers to form new
alliances that can produce a new era of optimism and a healthier
respect for the needs of others. I had originally supported John
Edwards for President, but with his withdrawal I am voting for Barack
Obama. People will, and should, make their own choices, but I believe
that, while both remaining candidates would make outstanding
presidents, Senator Obama has the best chance of giving this country
the new beginning it so desperately needs."
