That's likely true, especially when you have a pro-'Rat pollster, which is probably the case in whatever poll(s) this Huff Post writer is citing.
But when he comes up with Sanders beating Walker in a head to head matchup, I'd like to know what percentage of those questioned even know who Sanders and Walker are. My guess is that name recognition nationally is very low for both at this stage of the game. So I'd call the result of this poll meaningless.
Cruz
That is all.
Sanders couldn’t beat Walker or any other competent GOP candidate, which is why he will not be allowed to beat Hillary.
