Poll numbers released Sunday show tightening races in both the Democratic and Republican primary contests on Tuesday.

In the weeks leading up to the Illinois primary, Hillary Clinton and Donald Trump both had double-digit leads in the polls. But a CBS News poll of likely primary voters released Sunday shows Illinois in play. Bernie Sanders leads Clinton in the poll 48 percent to 46 percent. It’s a sharp contrast from last week’s Chicago Tribune poll, which had Clinton leading by 42 points.

On the Republican side, Donald Trump still leads Ted Cruz, but the gap has narrowed to 38 percent to 34 percent. John Kasich is polling third and Marco Rubio, the only Republican not to campaign in Illinois last week, is polling fourth.

The presidential hopefuls are making their final rounds across the state on Monday, election eve.

Polls are open today in Illinois from 6am to 7pm, and anyone in line by 7pm will be allowed to vote.  Tune in to the Big Z for local and state election results tonight on the half hour after the polls close.
