The proposed changes still have to win approval, but if they do, a Senate race which another prominent Democrat is not likely to enter may be Donnelly's best option.
For his own part, Donnelly said Republicans aimed to make the district more friendly for themselves, but he remains confident that a Democrat can win in the 2nd District -- even if that Democrat isn't himself.
"Even though it appears that politics played a role in the drawing of this map, I am confident that a Democrat can win in the new 2nd Congressional District. Then-Senator Obama performed well in this district in 2008, earning 49% of the vote," said Donnelly. "Also, it is not uncommon for a Democratic candidate in Indiana to outperform his or her nominee for president. I did it in 2008, outperforming then-Senator Obama by 13 points, and I know it can be done again.
Donnelly also said that he would have a decision on his own political future very soon.
"As for my future plans, my decision will ultimately be based on how I can best serve the people of this great state. I will soon be sitting down with my wife and children and expect to make a decision in the coming weeks," he said.
