Second, even if Republicans do win the White House and Senate in 2012, how much appetite will they then have for that 1-page repeal bill? Suddenly it will be their town halls filled with outraged senior citizens whose benefits are threatened; their incumbencies that will be threatened. Already we are hearing that some Republicans wish to retain the more popular elements of the Affordable Care Act (ACA). Which means the proposed 1-page bill will begin to grow…

Fourth, Republicans will find the task of writing their “replace” law even more agonizing than the Democrats found original passage. The party has no internal consensus on what a replacement would look like. Worse, any replacement of the law’s popular elements will require financing. But where is that money to come from? New taxes are unacceptable. The proceeds of “closing loopholes” are already spoken for—that’s how President Romney has promised to finance his promise to cut the top rate of tax 28%. And he’s also promised to increase defense spending.

Fifth, the clock is ticking. President Obama passed the ACA in the second year of his administration. A President Romney will have to pass repeal in the first year of his, because the law goes into effect in 2014.
