Yes. Republicans historically get 92-93% of their base, while Democrats secure 88-89% of their base.
Both Romney (90%) and Obama (86%) are underperforming with their base.
I find it hard to believe that Romney won’t get 94% or so of Republican voters on 11/6.
I fear that the Republican percentages are accurate. There are people in the Republican party that simply will not, under any circumstance, vote for a Mormon.
