If and this is a big IF the contractors were going to cover the costs and operating fees and the state didn't have to pay back the fed, yeah, big mistake on the Gov's fault but that article you link to... makes me doubt that is the whole story.
take a look at this.
Well, that means that if the project is shut down.. let's say the contractor agree's to pay cost over run.. and it does equal to 1 BILLION dollars... after a few hundred million the company stops work and declares bankruptcy. The project is unfinished and now Florida has to repay the 2.6 billion and has an unfinished project. You see, the quote uses past tense.. meaning that boat has sailed and Florida would be on the "hook" (going with a fishing theme here).
Also, here is another article that says Florida has to pay part of the project, almost 300 million dollars, see the above post about ridership.

Also, here is one discussing how tax payers are already covering operating losses of existing rail lines that are cheaper than the high speed costs. For example.. The New York MTA had to get 600 MILLION last year to help cover their losses (not in this article).

I know that for the first time home buyer tax credit that was for last year, it had a clause that you cannot sell your house for so many years... I'm sure there is a clause about the high speed rail project and shutting it down (read bottom link about one exact same situation). Now you can say a private business will cover the costs all you want but they have the ability to declare bankruptcy, have insurance from multiple companies that might help them with those costs etc... a state does not have that luxury, they can either raise taxes (which, is a huge hurdle) or cut spending (read: eliminate jobs, state programs, schools etc...) Now.. if you can't see how a high speed rail project between 2 towns 90 miles apart that costs 3 billion dollars and will have potentially high operating costs MIGHT cost the state of Florida a lot of money.... there is nothing more I can say to help you understand what it is I am talking about.
Now, I'm cool with tax payers covering high speed rail costs as long as there is a tax increase to offset that deficit. Charge 8 cents more per gallon or something but with the deficits being the way they are... and every state looking at making cuts, I can see why Scott (not saying that is Scott's reason) would balk the project. If it's political, then fuck the dude but we won't know that unless he opts to run for President or a new piece of news comes out.
I'm down with High Speed rail, if it is economically feasable.. California to Nevada, hell ya! We're talking about millions upon millions of people per year dealing with TSA bullcrap, waiting in an airport for an hour or two before hand.. taxi on the runway vs. hopping on a train ... I'd buy STOCK in that train company because it's a winner.
