Is this the most partisan opposition pairing for POTUS ever?
Mitt Romney just picked Paul Ryan for his running mate. Ryan is fiscally and socially conservative, to a degree that will turn off a lot of independent voters. This may have been a selection to appease to the conservative republicans who felt that Romney was not conservative enough, but it won't help in the general election when they will need more than just the republicans.
Have we seen a more partisan pairing before? Usually each party tries to select one person they can portray as someone willing and able to work with the other side, but neither Romney nor Ryan can claim that.
