has a lot to do before he is nominated for the Republican party for the general presidential race.
He has to raise money for the general election, raising as much as he can.
He has to get more workers who are dedicated and send them to states that are important for him to win against President Obama in the general election.
He has to get his message across and attract all different sorts of voters who have a wide variety of opinions.
The most important is he has to win the nomination while his opponents are taking his votes because they won't get out of the race, perhaps because of hubris.
The next election is April 24 and Pennsylvania and a few other northeastern states will be voting.
