"It's now up to Jeb Bush. Let's see if Jeb's got the courage to do the right thing. If he doesn't, his political career will be over as far as I'm concern."
And if he does, his political career will be over, as well. In fact, if he does not act, he will simply serve out his term as Governor. He cannot run again, in any case, for Governor of Florida.
He will run, I imagine as a Senator at some future time.
If he acts in defiance of Greer's order, however, I would be willing to bet he'd be removed from office, under whatever impeachment or recall process Florida has.
While many people are adamant about this case, that is true on both sides. A Governor who acts illegally, and is found to have done so, is likely to lose his office forthwith.
That is why you do not see President Bush doing any foolish things with regard to this case, too.
Who's gonna remove Jeb if he acts. Greer and what army? How is it illegal if he makes an executive order to do so? If Jeb doesn't act, he will lose all future political bids and ambition. He will have shun the conservative base. I'm here in FL and if Jeb doesn't act, I will work damn hard against him if he chooses to run for the US Senate.
