I can't shake the feeling that whoever wins in 2016 will be a one-termer

[Lord of the Dome]

I'm definitely beginning to feel that way as well. I can't help but feel as though the continued stranglehold that the Republicans have on congress, which I think will be maintained for the forseeable future, will hinder both a future President Clinton in trying to advance any kind of agenda and a Potential future Rubio/Cruz/whatever by allowing them to go further than their mandate should allow, thus alienating the public at large. In both cases I think that this would be toxic to the incumbent and put them in potentially quite poor circumstances by the time 2020 rolled around.
