"Pork" is what goes to other states or congressional districts. If it comes home, it's "bacon."
And that "bacon" has gotten people reelected for as long as anybody can remember. To carry the analogy a step further, what we've seen in the healthcare reform process is nothing new; it's the same sausage-factory which Congress has been from the beginning of the Republic. The only difference is that the media coverage and heat surrounding the issue have exposed us to things we never paid attention to before.
On healthcare reform, the GOP bet the ranch that, if they refused to participate, the Dems could never put a package together to get the 60 votes they'd need for cloture in the Senate. They nearly succeeded, but the cost of their gamble was loss of all control over the process.
Now the law will be there as a platform which can be amended when needed. Call it a Trojan Horse if you like, but it will operate more like a trigger: if the insurance companies continue to jack rates through the roof, you'll see their antitrust exemption go away, and/or a public option established and/or Medicare expanded to compete with them.
And Joe Lieberman? Dead man walking.
