Danbury Mayor Dean Esposito will present his first budget to the City Council when the group meets tonight.  Republicans have a 14-7 super majority on City Council and they will be voting on the tax and spending plan at their May meeting.  A rally is planned in advance of tonight's 7:30pm meeting.  A group called Danbury Defending Public Education is holding the rally outside City Hall starting at 6:30pm to call on the Mayor and Council to fully fund the Board of Education's 6.2 percent spending increase.  The Board of Ed budget is proposed at $152 million and would use some reserve funding and federal grants to offset some of the increase.
