Donald Dumb (thanks HK
) really does not know what it takes to be President, only that he wants the job and believes he will do the best job. And now he has a clear path to the nomination because of the anti-establishment mood of the GOP electorate.
In the general election it's not whether his weaknesses are exposed (simply put he is totally unqualified), but who he is going to be up against. Weaker candidate lose. Kerry and Romney are recent examples.
