Donald Trump say Republican Ted Cruz can't run for President, is he right?

No, they can't. Anyone who meets the proper requirements to get on the primary ballot (generally just amassing a certain number of signatures) can run in the primary in a state. Now there is a limitation on Trump's ability to run as an independent candidate, like he has threatened to do.

Several states have "sore loser" laws which prevent someone who has appeared on a primary ballot from running in the general election if they lose. These laws would keep Trump from running in several states and would all but certainly keep him from winning the election.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
