What this means is that "party" has devolved into spots on a ballot.
We saw it with Arlen Specter, who went from being a Democrat to being a Republican to being a Democrat again, just to get on the ballot.
We saw it with Michael Bloomberg, who ran for NYC Mayor as a Republican only because all the spots on the Democrat side were taken. He eventually switched to Independent after winning.
We saw it with Charlie Crist. We saw it with Joe Lieberman. They went the Independent route.
At least Lisa Murkowski stayed a Republican and went the write-in route. And Phil Gramm resigned as a Democrat and asked the voters to reelect him as a Republican.
If they switch parties solely for ballot access, then that means they have no core beliefs other than wanting to hold an office to rule over others.

I totally agree, no core beliefs
