I live in Baltimore County, MD. I have voted Libertarian in three of the last four elections. Didn't like Dole, wasn't happy with Bush in '04 and didn't like McCain. It is easy to make these protest votes as MD always goes to the Democrat by 10-20 points. I see a wave developing this year, however. I will absolutely vote for Romney (Ryan as VP helps) as I believe there is a small chance that this wave hits states no one expected. PA is Romney's, barring anything crazy happening in the next three weeks. There have been no recent polls in places like MD and NJ. The Gallup numbers for the white vote, Jewish vote and tightening of the female vote are pointing to a possible landslide. My vote might actually count this year, and I cannot withhold a vote for the man who is our chance to rid ourselves of Obama, my own differences with Romney aside.
PA, NH, VA, OH, WI and FL are going for Romney. I think the shock and awe will come when a state or two like MD, NJ or OR comes along for the ride.
