Whoever wins the Hillary/Obama deathmatch will lose at least 19% of the other candidate's supporters, and as much as 28%.
This is not just losing, it's getting blown out.
Furthermore, the GOP is not likely to lose as many voters. On the one hand, Hillary engenders a fierce response from them. On the other hand, Obama's pastor caused a controversy that Obama has not handled well. This translates into a blowout win.
The conservatives who demanded ideological purity on immigration and elsewhere? Out of luck. John McCain will, in all likelihood, win without them.
They forgot one simple lesson: The winner decides the terms, not the loser. Now, McCain will win, and he will have a level of support in the general election that will likely be a mandate.
In other words, he will have the support to pass things like comprehensive immigration reform.
Conservatives gambled and lost. The consequences are going to be painful for them. Maybe now, they will learn that half a loaf is better than nothing.
