The Senate approved Gov. Martin O'Malley's proposed expansion of early voting Monday night, sending the legislation to the House of Delegates.
Senators voted 35-12, with most Republicans opposed, to increase the number of days and hours that early voting centers will remain open.
O'Malley's proposal follows a presidential election that saw voters waiting in line for hours at the limited number of early voting sites in each county.
It would also increase the number of voting centers in the state's largest jurisdictions -- Montgomery, Prince George's and Baltimore counties -- from five to eight and permit same-day registration and voting at the centers. Frederick County, which now has a single site, would expand to three.
