Now, for those individuals and small businesses who still can't afford the lower priced insurance available in the exchange, we'll provide tax credits, the size of which will be based on your need. And all insurance companies that want access to this new marketplace will have to abide by the consumer protections I already mentioned. This exchange will take effect in 4 years, which will give us time to do it right. In the meantime, for those Americans who can't get insurance today because they have preexisting medical conditions, we will immediately offer low-cost coverage that will protect you against financial ruin if you become seriously ill. This was a good idea when Senator John McCain proposed it in the campaign, it's a good idea now, and we should all embrace it.
