Sure looks to be shaping up this way, but the Democrat-Socialist's ace-in-the-hole is that if the Republican leadership is not replaced in both houses, the Congress may be more conservative but they will not function more conservative.
The GOPE leaders and caucus members who profess to defend the Constitution and promote traditional American values demonstrate time and again they do so only when it is convenient for them to do so.
Their real ace-in-the-hole are the recipients of the hundreds of billions of dollars of government largesse. How hard would you fight to keep a million dollar a year cash flow coming? Now multiply that by a 1000.
