INDIANAPOLIS -- Millions of dollars are already flooding into Indiana's Senate race between Evan Bayh and Congressman Todd Young.
A national, non-partisan analysis shows the race has tilted Democrat, after it was one-considered Republican-favored.
That change has led the Koch Brothers and the Democratic Senatorial Campaign Committee to get more involved with seven-figure ad buys.
With control of the Senate at stake, Indiana has become a focus for Republicans and Democrats at the national level.
IUPUI Associated Professor of Communication Studies Kristy Sheeler says Bayh's entry into the race factors into the tone.
"It's a big name," she said. "He doesn't have to go through the early introductions to voters. Voters already have a sense of who he is."
The Koch Brothers' super PAC is spending $1 million to attack Bayh. The Democratic Senatorial Campaign Committee confirms it has also earmarked $1 million for ads against Young.
Sheeler says voters shouldn't expect the negative tone to let up before Election Day – in fact, it's likely to get even nastier.
