Keep in mind GWB was president and had majorities in both the HOR and US Senate. He started a lot of the initiatives that Obama followed through on during that time.
We really are dependent on a conservative HOR inspiring Senate conservatives.
Here’s their math (remember, this is NOT a Presidential election, it is state by state ):
There are states to concentrate on and they fall into two groups .... “Take Back” states and “Upgrade” states as follows:
Take Back (from Dem incumbent)
North Carolina Hagan
South Dakota - Johnson
West Virginia - Rockefeller
Upgrade (from lesser conservative)
South Carolina Graham
Wyoming - Enzi
With the exception of Colorado (should be GOP), every state went Romney in 2012.
