Joe Andrew, who Bill Clinton appointed Chairman of the Democratic National Committee in 1999, has just switched his support from Hillary Clinton to Barack Obama.   Andrew has been a supporter of Sen. Clinton since she first announced her bid for the presidency.  Andrew made is announcement at a press conference in his hometown of Indianapolis, Indiana Thursday morning.   During the press conference Andrew encouraged his fellow Democrats and Hoosiers to end this madness and unite behind Barack Obama for Tuesdays primary.  In his telephone interview with the Associated Press Andrew said “I am convinced that the primary process has devolved to the point that it’s now bad for the Democratic Party.”  Andrew also cited additional reasons for his switch in a letter to superdelegates.  In the letter the former DNC Chairman says ”a vote for Hillary Clinton is a vote to continue this process, and a vote to continue this process is a vote that assists (Republican) John McCain.”  Andrew went on to say  “[w]hile I was hopeful that a long, contested primary season would invigorate our party, the polls show that the tone and temperature of the race is now hurting us,” Andrew continued. “John McCain, without doing much of anything, is now competitive against both of our remaining candidates. We are doing his work for him and distracting Americans from the issues that really affect all of our lives.”  Andrew said that teh Obama campaign never asked him to switch his support but he did so after witnessing the principled way that Obama has handled two recent issues that have challenged his campaign.  The Wright controversy and the gas tax holiday qestion.  Andrew praised the fact that Obama stuck to his guns with respect to the gas tax holiday even though the politically expedient thing to do would have been to go along with Clinton and McCain on this issue.  And, he also praised Obama’s handling of the Jeremiah Wright controversy saying that Obama “has shown such mettle under fire.”  Andrew’s decision also increases Obama’s superdelegate count thereby clossing in on Clinton’s current lead.  The current count for superdelegates 247-263 Clinton.  However, Obama leads in the delegate count overall 1735.5 to 1597.5 for Clinton.  Last count, 230 superdelegates remain undecided, and about 60 more will be selected at state party conventions and meetings throughout the spring
