The legislative body can set what ever tax rate if any that they want. Direct bribery is illegal, but crony capitalism plays both ways.
What are you trying to say? Why are you avoiding the actual question being asked?
Of course they can set tax rates etc. That is part of their job. But can they dictate to a business to give a discount to a specific organization in order to get support for a piece of legislation? And what if that organization is a contributor to the public servant making that statement/requirement?
The action is legal, passing a tax law that just doesn't give a special break to aviation fuel is fine (though only hurts Atlantan's really, increasing the costs for them at their airport, all airlines will just pass through the cost). But the statement attaching it to giving a discount to a specific group is the part that is questionable at best.
Not based on Cagle's comments. A reasonable deduction can be made that Cagle wouldn't have moved to kill the measure had the NRA issue not materialized. I thus dispute that this is legal based on that, given that Cagle had not expressed any opposition prior. Because that was his first statement, he was using his position as a public officer to attempt to extract a benefit for members of the National Rifle Association in the way of discounted fares. That's actually illegal. If Delta sues, it should be noted that the only office Democrats dominate in GA is the state Supreme Court, and the lawsuit would be in Atlanta, another case friendly to Democrats...with Republicans having to defend the case.
As for the next move for Delta, it will depend on the result of the election. If Cagle wins the nomination and then the election, he doesn't want to be known as the man who chased Delta out of Atlanta. Of its flights, the trans-oceanic flights can be moved to other hubs or transferred to JV partners, or even Kenya Airways---remember they're starting NBO-JFK in W18 which means DL no longer needs to fly ATL-JNB, instead doing an ATL-JFK-NBO-JNB routing, with JFK-NBO-JNB on KQ metal, and could reallocate the planes to a service like LAX-TLV or DTW-HKG if a slot can be garnered). Other Africa services can be flown through JFK now that JFK-LOS is coming in S18. DL can have its ATL services reduced to being a Caribbean and LatAm network on its own metal.
The other consideration besides DL is Amazon. Reportedly, Atlanta was one of the top finalists for HQ2...Amazon is now expected to pick Northern Virginia instead. If Bezos is smart, he will wait to make the announcement until it's too late to replace the Republican candidate.
