Yeah. Quite seriously, when you're all in name anyway, you might as well just go ahead and make the jump. Better you be honest about that and the fact that the other national party is really a better fit for you than your current one (*coughcough*Zell*coughcough*).

And if your constituents didn't know that you were basically all in name part of the other party anyway... well, either you did a really good job covering up your job record and opinions, or you have free reign to do whatever you want because they don't care enough to double-check you anyway.
