2010 being an exception with the 700+ seat changes, for the most part, an incumbent only loses his seat when they retire.
His reelection is assured.
Wait 'til 2012! If ya think the last one was a landslide, I predict we're gonna take a majority in the senate, the presidency, and add to the house! That doesn't even account for the in-state races! By shovin' legislation down our throats and triplin' the deficit our kids and their kid's kids will have to pay for, the Rats have shot themselves in the ass! Especially given their answer is to spend more money we
don't have in order to "help" the Obiewan economy.
Better than 60% of America is flat ****in' fed up with these, "**** the next 2 generations, we're spendin' now", Rats!
ETA:
At least all my friends and neighbors are! Of course we all work, or
have worked, our ass off to spend our time on the porch, to keep what we have without the Rats stealin' it from us.
