Donelly was first elected to Congress in 2006 and won re-elections in 2008 and in 2010.
The National Republican Senatorial Committee released a statement regarding Donnelly's announcement, saying:
"Just months after voters overwhelmingly rejected Brad Ellsworth's liberal policies, Joe Donnelly wants to sell Hoosiers on that exact same big-spending, job-killing Washington agenda. We welcome him into the race and look forward to him campaigning side-by-side with President Obama. Just like Ellsworth, Donnelly has been a partisan rubber stamp for liberal Democrat leaders in Washington, helping them ram through ObamaCare and the failed $787 billion stimulus debacle. Hoosiers have made it clear that they're not interested in more reckless spending, tax hikes and out-of-control debt in Washington but Democrats like Joe Donnelly have long ignored the voices of Indiana's families and job creators, and that's why we're confident this seat will remain in Republican hands."
The Democratic Senatorial Campaign Committee fired back with a statement of their own:
"Joe Donnelly's decision to run for the U.S. Senate is great news for Hoosiers.He is a strong candidate who knows how to beat the odds and win tough campaigns. Most importantly, Joe is exactly the kind of tireless fighter Indiana families need to rebuild the state's economy, create jobs and get Hoosiers back to work. With Joe Donnelly in the race, Indiana will be a great pick up opportunity for Democrats next year."
Statement from Indiana Democratic Party Chairman Dan Parker:
"This is a great day for Indiana Democrats and an exciting announcement for 2012. Joe Donnelly is a tireless advocate for Indiana's middle class, and he'll do in the U.S. Senate what he's done as Congressman in the Second District: fight to make sure Hoosiers have jobs and can earn a decent living in order to take care of their families and retire with dignity. It doesn't make any difference who Joe runs against next year. Hoosiers want a new U.S. Senator, and he's the best candidate for the job. He's a proven winner in tough elections, and he'll be a great U.S. Senator for Indiana."
