A day usually devoted to feel-good events for Illinois Democrats could be tense this year as unions protest a decision by Gov. Pat Quinn regarding promised raises.

Democrats will be gathering Wednesday for Governor's Day at the State Fair, a day when party leaders rally the troops and promote candidates.

Unions are angry that Quinn is trying to cancel raises promised in state labor contracts. Quinn says Illinois doesn't have enough money to pay the raises, but the unions disagree and say government should keep its word.

The AFL-CIO and about 10 associated unions plan a news conference Wednesday and a protest outside the main Democratic rally at the fairgrounds.

Unions are a key source of money and manpower for Democratic candidates.
