The class size amendment was barely passed by Florida voters in 2002.
Then-Gov. Jeb Bush led the charge against the amendment - which called for capping class sizes in public schools - by saying the cost of the amendment would "blot" out the sun.
Bush tried to get the Legislature to freeze or even scale back the amendment, but his efforts came up short, most notably in 2005 when it was defeated in the GOP-controlled Senate by a 21-19 vote.
Flash forward to this year when it looks inevitable that a new measure to change the class size caps will clear the Senate. Republicans who opposed it five years ago have flipped their votes and not even all Democrats are standing in opposition.
Still some Democrats are wondering why Republican legislators are doing this. They say the final restrictions required by the amendment can be met by changing state law to give districts some wiggle room.
Republicans say that they can't ignore the constitutional requirements and that the final caps that kick in this fall are just too expensive to pay for.
But it's worth noting that the original 2002 amendment was championed by U.S. Rep. Kendrick Meek, D-Miami and the likely Democratic nominee this fall for U.S. Senate.
If the class size do-over is on the ballot, then Republicans would be able to point a finger at Meek and ask why he wants to impose expensive restrictions on schools at a time the state is grappling with budget problems.
Remember it was Bush who used the original class size amendment as a way to brand his Democratic rival Bill McBride as a tax and spend liberal. During his entire 2002 re-election campaign Bush kept asking how McBride would pay for class size. Now of course Alex Sink - the husband of McBride - is running for governor and she could have to deal with the same question.
