Exactly! If we do not win the Senate, OBAMACARE is here to stay.
And Dodd-Frank, Sarbanes-Oxley, etc. Not to mention defense cuts, repeal of the Bush tax cuts. Romney's got up there in 2 debates and not once advocated for the idea that he'll need Republicans to win the Senate to pass most of his agenda. Instead he's advocated for "bipartisanship," which is just going to make those squishy independent voters split their ticket between Romney and the Democrat Senate candidate.
If Romney is elected without the senate he can still delay Obamacare year to year UNTIL we get the senate back.
