Primary Update: Do Hillary and Trump have Things Locked Up?

It's time for our weekly look-in at the 2016 presidential races. Big wins in New York by the two front runners, Hillary Clinton and Donald Trump, are the key development this week. The key question is whether this translates into nomination gold for them. We'll look first at the Democrats and then the Republicans.

Democrats

Hillary Clinton's 16-point 58 to 42 percent win over Bernie Sanders gave her a delegate edge of 139 to 106 in the Empire State. That lengthens her delegate lead by 33 in the race for the nomination. In the overall count of pledged delegates won in primaries and caucuses she now has 1428 to his 1151. There are 1472 pledged delegates left to win in the states that haven't voted yet. A total of 2026 secures the majority, so Hillary would need 598 of those, about 40.5%. Bernie would have to win 875, about 59.5%. He'd have to win the remaining contests by an average of 19 points to overtake Hillary. Is that possible?

To find out, let's look at what's coming up in next Tuesday's votes. Five Northeastern states will be in play on April 26, all holding primaries. All Democratic contests award delegates proportionally to the vote. So, does the Bern look to have a good chance to do some catching up? Well, if the polls are anything close to accurate, not so much. Pennsylvania is the big prize, 189 delegates. Hillary leads there by 16 points in the average of recent polling. Maryland offers 95 delegates, with Hillary up by 21. Connecticut has 55 and Hillary leads there by an average of 7. Then you have two small states with only one recent poll in each. Rhode Island has 24 delegates and the one survey there had Clinton up by 9. Delaware will send 21 delegates to the convention in Philadelphia, and the one poll taken there this month showed Hillary ahead by 7. If these polls are right, and most recent polling this primary season has had good accuracy, the former Secretary of State will win 219 delegates next Tuesday and the Vermont Senator will pick up 165.  That means another 54 added to Clinton's lead.

So it's looking more and more that the Democratic nomination is effectively wrapped up. After those results next Tuesday, Sanders would have to win all the remaining races by an average of almost 30 points to catch up in pledged delegates. And if you add in the super delegates it's even more certain. Hillary has the support of 502 to Bernie's 38, with 172 still undeclared. With them counted into the mix Bernie would need a whopping 72 percent of all the still unchosen delegates to win at the convention. The bottom line? It's all over but the shouting. Hillary Clinton is the 2016 Democratic nominee.

Republicans

On the GOP side the main question is whether Donald Trump can clinch the nomination on the first ballot of the Cleveland convention. After taking 60 percent of the vote in his home state to 25 for John Kasich and 15 for Ted Cruz, Trump walked away with 89 delegates to Kasich's 3. He now has 845, followed by Cruz with 559, Marco Rubio, who has suspended his campaign, with 171, and Kasich with 148. Trump needs 1237 for a first-ballot convention triumph and there are 674 Republican delegates still to be awarded in the upcoming states. That means The Donald would need to get 392 of them, a little over 58 percent. Is that doable? Well, it looks like it's going to be very close one way or the other. He could just make it or could fall just short. Complicating matters are the varied and sometimes bizarre delegate selection formulas used by Republican parties in the different states.

Here's how things stand in the five April 26 Republican primaries. Pennsylvania has 71 delegates and the polls say Trump 44, Cruz 25, Kasich 24. Maryland gets 38 and the race is similar to Pennsylvania's, Trump 41, Kasich 26 and Cruz 25. Connecticut, 28 delegates, has Trump at 49, Kasich 27 and Cruz 18. Then come Rhode Island and Delaware, with only one poll each, as with the Dems. RI has 19 delegates and the one poll from February gave Trump 43 with Cruz and 10 and Kasich at 14. Rubio had 25 percent support back then. Delaware has 16 delegates and the one April poll showed a big lead for Trump: 55 to 18 for Kasich and 15 for Cruz. In terms of delegates, as near as I can figure given the different rules in play in each state, Trump stands to win 71 delegates, Cruz 12 and Kasich 18.

Then there are 54 delegates to be elected in Pennsylvania's 18 congressional districts, three per district, who are winner take all by district, but who are not bound to vote for the winning candidate of their district once they get to the convention. Talk about strange. Depending on who those delegates are and how they are selected, they could vote for anybody even if Trump wins their district. And judging from the polling there, one would expect Trump to win most of those districts. But GOP insiders do not have much love for Trump, so who knows what they might do if Trump's campaign apparatus can't insure their supporters occupy those seats. If they can, Trump would come away with 105 delegates next Tuesday to Cruz's 22 and Kasich's 28.That would leave Trump at 950 delegates, needing 287 more to get to the magic number with 539 still to be elected in the remaining states. That outcome would bring Trump's needed percentage to clinch down to 53.2%, seemingly a doable feat, especially considering he is running 9 points ahead in delegate-rich California, which awards most of its delegates to congressional district winners on a winner-take all basis. But if the insider game denies him those votes, he would need 63 percent of the rest of the unchosen delegates to win on the first ballot in Cleveland, a much taller order. The bottom line on the Republican side is that it's nip and tuck and could go either way. It should be pretty dramatic to watch.
