Forget that that is a pretty tall order, consider the prospects of trying to round up enough Republican votes to undo an entitlement even if the Republicans managed to pull off total control.
Fast forward in time when Obamacare is in place and people are relying on it for their health care needs. Certainly you can hear the cries from those objecting to taking Obamacare away.
Pick the most ill person as a prop for the Democrats, one that will at the time be receiving life saving treatment they would not have had without the plan. Unless the Republicans have that much spine - something they did not show for eight years on much less touchy issues - it aint gonna happen.
If Obamacare passes, the best that those opposed to it can hope for is to see adjustments to Obamacare to mitigate the damage it will do.
If that is Romney's plan, raise the white flag now.
Now, Romney has merely said what I outlined a week ago.
Winning the House in November 2010 is sufficient to put a stop to funding AND taxes, by simply declining to vote for that. We are back to status quo ante. The people who were “depending on it” never saw it; they never even got taxed. (If withholding raised in 2010, they’ll get refunds.)
Winning the Senate and Presidency in November 2012 will at the least allow the plan to continue to be starved. If a filibuster can be broken, then the plan can be killed.
