FRANKFORT - Rand Paul has ended his presidential campaign after a fifth-place finish in the Iowa caucuses. But the lasting impact of his once promising presidential bid could be a caucus in his home state.

Kentucky Republicans changed their election calendar to hold a presidential caucus March 5 so Paul could run for president and re-election to his U.S. Senate seat without violating a state law banning candidates from appearing on the ballot twice in the same election. Paul even donated $250,000 to pay for the caucus himself.

Now that Paul is out of the race, he's not backing away from the caucus, but he'll be footing the bill for Ted Cruz, Marco Rubio, Donald Trump and other candidates to contend for Kentucky's 46 Republican delegates.
