Last night’s celebrations for Democrat Joe Donnelly’s big upset in the U.S. Senate race is getting doused by cold hard reality today. That’s because Republicans can now claim to have supermajorities in both chambers of the Indiana legislature.

While the GOP already had a supermajority in the Senate, a few key wins gives it a supermajority in the House as well. Republicans now have 69 members in the House, two more than the 67 needed for a supermajority in the 100-member house.

“We have had excellent candidate recruitment and Hoosiers have elected a group of leaders who already have a track record of job creation. The majority of our new members are small business owners who have experience meeting payroll, balancing budgets, thinking about the bottom line, and creating and retaining jobs,” Indiana House Speaker, Brian Bosma (R), said Wednesday while meeting with the entire Republican House Caucus.

One race that helped the GOP is the victory in the Democratic stronghold of Lake County, outside Chicago. That’s where Republican Hal Slager won in the 15th House District, which includes the town of Schererville.

Having a supermajority allows Republicans to conduct business without Democrats present.

In each of the past two years, House Democrats have walked out to stall Republicans from pushing through measures like school vouchers and right to work laws.

But Democrats won’t be able to do that anymore.

Despite its new power, Bosma says the GOP will work in a bipartisan fashion.

“Hoosiers told us they want their state to live within its means, promote job creation and prepare today’s students for tomorrow’s jobs. Hoosiers have spoken, and have elected 19 new members to our Caucus,” Bosma said.
