Glendening/Townsend didn't squeak by. They outright stole that election by keeping the polls open in Prince Georges County and Baltimore City past the mandated closing time of 8PM. Both of these regions are majority black, Democrat party areas where Democrats scream "racism" if Republican poll watchers should show up to see that the election is kept honest in these areas. Most are not even watched because Republican poll watchers fear for their own personal saftey should they set foot in these areas. The DemonRATS jack up the vote totals without any fear of being caught. Just watch this November; when Townsend is behind by five or six thousand votes, suddenly around 12 or 1 AM she will be ahead by that amount. DemonRATS will claim that the polls needed to be kept open because the "lines are too long" and everybody should get a chance to vote. That's how it's done in the People's Republic of Maryland. I live here and I've seen it happen.
Glendening also got 100% of the vote from several nursing homes where many of the patients were suffering from advanced stages of dementia.
