The latest poll in the Maryland governor's race shows incumbent Martin O'Malley with a 6 point lead over potential rival, and former governor, Bob Ehrlich - the race stands at 49% to 43%. The new survey, by Rasmussen Reports, shows a closer race than a poll conducted last month, and a near halving of O'Malley's lead since a poll conducted last September. Like every poll on the race it shows that O'Malley simply cannot crack 50% and polling below 50% is a bad sign for any incumbent, but the Maryland race is a bit unusual as it pits two governors against one another. Ehrlich may not be the incumbent, but he cannot seem to make it into the mid 40s. Maryland is a tough nut for any Republican candidate to crack with a 56% to 27% voter registration advantage among Democrats. Ehrlich carried the day in 2002, but came up well short in 2006. He'll need a strong GOP electoral wind come November to help carry him over the top.
