Hillary Clinton and Bernie Sanders are locked in a razor-thin race in Indiana

Hillary Clinton and Bernie Sanders were locked in a tight battle in Indiana's Democratic primary Tuesday night.

With about 30% of precints reporting in the state, Sanders held a slim, single-point advantage over the former secretary of state.

Recent polls showed a tight race between the Democratic presidential rivals in the Hoosier State.

Yet even before Tuesday's contest, Clinton maintained a significant lead in popular votes and pledged delegates. That means it is unlikely that Sanders will be able to catch up to the former secretary of state unless he scores massive upset wins in remaining contests like California, where he currently trails in most polls.

But Sanders has suggested recently that he does not plan to get out of the race anytime soon.

In a Sunday press conference in Washington, DC, the Democratic presidential candidate promised repeatedly he would take the campaign to a contested convention. And after briefly appearing to halt his rhetorical jabs at Clinton, the Vermont senator reprised his attacks on her alleged coziness with the financial industry.
