I hope not because that would be utterly tasteless. I think America will be turned off by little Ronny and democrats trying to cash in on Ronald Reagan's legacy this way. President Reagan was loved because of his convictions and American's will see this for what it is which is a cheap shot at Republicans and President Bush43.
If Michael Reagan wants to speak at the GOP convention then he should. But to have the GOP ask him to speak because Ron is going to speak at the Democrat convention just seems tasteless. It would be seen as two parties trying to cash in a dead man's legacy. It would not look right.
I think Michael can answer whether or not it is "right" or "wrong" the best, and if he does or doesn't it won't offend most Republicans.
But if he does, it will definitely offend MOST DEMOCRATS.
