Nor should they be. House Dems may not want to reserve their U-Haul truck to take their junk back home just yet, either!!
But, just for fun, let me play devil's advocate. What if the 'Pubbies take control of the Senate AND the House??? What then?? If history is any value, their stewardship of these houses of Congress will be no better than the Dems' has been. They did okay in the early days of the Contract with America, but the bloom was quickly off the rose when they allowed themselves to be seduced by their lust for power.
As we all know, their abandonment of their conservative roots led to the losses in '06 and '08. So, what has changed in the last 2 years in the GOP (aka Stupid Party) to make us believe that a return to power of the GOP is going to be America's saving grace!!??? They are as bereft of ideas as the Dems and all we are going to do is repeat the acts of the past in hopes that they will yield a different result in the future. They won't. The 'Pubbies will simply lift a corner of the carpet and sweep the dirt under it because it's easier and won't interfere with Happy Hour at the club at 5 o'clock!! IOW, NOTHING will get fixed. The 'Pubbies are NOT the good guys on white chargers coming to rescue us.
In short, they are gutless politicians (like the Dems) whose sole concern is their next election (like the Dems) and being overpaid (like the Dems) for screwing the country (like the Dems) that they have no devotion or dedication towards (like the Dems) and growing their power (like the Dems)!! So, in truth, what are we REALLY expecting them to do???
The fossil incumbents are beyond repair which is why they all need to be sent to pasture and the dour Grassley is one of them.
