Certainly, nothing can be said on Indiana Primary (6 May); anything can happen. There are equal number of Indiana polls favoring Sen. Hillary Clinton and Sen. Barack Obama. It appears that Clinton and Obama are sitting on an evenly poised seesaw in Indiana, which may tilt anyway.

Star / WTHR Poll conducted in Indiana between 20-23 April showed Obama leading Clinton with 41% to 38% democratic vote. With Margin of Error = 4.3%, the poll gave Obama 3 % points’ lead over Clinton. The poll indicated Obama’s “thin margin win” over Clinton.  

But then, the American Research Group’s Indiana poll conducted between 23-24 April showed Clinton leading Obama with 50% to 45% democratic vote. With Margin of Error = 4.0%, the poll gave Clinton 5 % points’ lead over Obama. The poll indicated Clintion’s win with 5% points .  

The Indiana Poll on 23-24 April by South Bend Tribune Conducted by Research 2000 showed Obama leading Clinton with 48% to 47% democratic vote. With Margin of Error = 4.9%, the poll gave Obama just 1 % points’ lead over Clinton. The poll indicated Obama’s “razor thin” victory over Clinton.  

Then again, the Survey USA’s Indiana Poll conducted between 25-27 April showed Clinton leading Obama with 52% to 43% democratic vote. With Margin of Error = 3.9%, the poll gave Clinton 9 % points’ lead over Obama. The poll indicated substantial win for Clinton.

The Indiana polls conducted in the later half of April articulate that both Clinton and Obama have equal chances of winning the Indiana Primary, but only one factor that puts Clinton little ahead in the polls is that – the polls favoring Clinton show her winning Obama with greater margin.
