A compilation of polls project Donald Trump and Hillary Clinton to do well in Tuesday's elections, according to Real Clear Politics.
On the Republican side, Trump is projected to win all five states. Polls show him favored in double-digits over his competitors.
On the Democratic side, Clinton is projected to win over Sanders in Delaware, Maryland and Pennsylvania. Polls show a tighter race between the two candidates in Connecticut and Rhode Island.
Delegates in the Democratic races are awarded proportionately.
Delegates in Tuesday's Republican races are awarded in a hodgepodge fashion.
• In Delaware, all delegates are awarded to the winner.
• In Pennsylvania, where 71 delegates are at stake, 17 delegates are elected without a commitment to a specific candidate. The remaining 54 delegates are free to vote for any at July's Republican National Convention, regardless of who wins the state.
• In Connecticut, Maryland and Rhode Island, Republican delegates are awarded based on statewide results and results from each congressional district.
Campaign cash raised in March:
Hillary Clinton: $27 million
