I don’t see Mikulski as being vulnerable. However, a year like this is the kind in which upsets happen. Never say never. Conservatives should at least keep an eye on this race.
Never.
I would love to see it but... never. Never ever. Is there a reputable poll showing Mikulski with less than stellar approval ratings? That alone would be shocking. The worse things get the more they LOVE Mikulski. Why? I have no idea.
Maryland politics (except for the local good ole boy networks in Southern Maryland and the Eastern Shore) are something that defy reasonable explanation.
Victories in New Jersey, Virginia and Massachusetts could be explained. Those standards cannot be applied to Maryland. Potential victories in other bastions of liberalism such as California can be explained. Not in Maryland.
