As Hillary Clinton and Donald Trump are celebrating after big wins in New York, their rivals are considering their next steps.
On the Democratic side, Bernie Sanders spent a rare day back home in Vermont, seen around noon leaving his Burlington home with his brother Larry. He returned to "recharge" before next Tuesday's round of primaries.
"There are five primaries next week," Sanders told reporters after returning late Tuesday night. "We think we're going to do well, and we have a path toward victory, which we are going to fight to maintain."
Earlier Wednesday, a group called "Rights and Democracy" delivered a 5000 signature petition to the Vermont federal building calling on the states superdelegates, including Sen. Patrick Leahy and Gov. Peter Shumlin to switch their allegiance from Clinton to represent the will of the 86 percent of Vermonters who voted for Bernie Sanders in the primary.
Massachusetts superdelegate Steve Grossman defended the process.
"These are the rules that were created some time ago," he said. "If the party leaders would like to get together and discuss/debate those rules for 2020 and beyond, I wouldn't have any problem doing that. That's what change is all about."
Grossman, a Clinton supporter, is a former Democratic national committee chair, making him a superdelegate for life. He was called by a Sanders supporter recently asking if he'd switch his allegiance.
Grossman believes superdelegates have the right to switch their votes, but he thinks it is unlikely to happen, "particularly because Hillary Clinton has received more popular votes and has more elected delegates by a margin of about 250 than Bernie Sanders does."
Grossman doesn't think the nomination will come down to superdelegates, but if it does, he says he feels comfortable with their wisdom and their judgement - which was the purpose behind the creating of the superdelegates in the first place.
As for the Republicans, Trump is back on the campaign trail following his big win in Tuesday's New York primary.
Campaigning in Indianapolis, Trump touted his victory over John Kasich and Ted Cruz as he and his team project a message of inevitability.
"I consider the primary win last night in New York to be the end of the campaign for the nomination and the beginning of the campaign now for November," said Geoff Diehl, the co-chairman of Trump's campaign in Massachusetts.
Diehl says, given the five northeastern states coming up next Tuesday, there is no path for Ted Cruz to catch up to Trump. But campaigning in Pennsylvania, Cruz insists, the race will go to a contested convention this summer.
"You may have heard there was an election yesterday. And as the media are breathlessly reporting, Donald Trump won his home state. Truly a remarkable achievement," said Cruz.
Diehl believes Trump will have the necessary 1,237 delegates at the convention. But if not, he says, "I think that's when you start seeing negotiations between he and John Kasich or another - Marco Rubio potentially - to cobble together that number."
Meanwhile, some of Trump's most ardent opponents are starting to notice a change.
"Last night we saw a measured sort of thoughtful guy, for Trump, OK, who acted more presidential," said Republican political consultant Pat Griffin, a Trump opponent. "He's still Donald Trump, but there was no reference to "lyin Ted."
Griffin thinks Trump is finally listening to someone - that his new convention manager, Paul Manafort, is successfully getting the candidate to tone down his rhetoric.
According to Griffin, Trump will end up being the nominee. But he says Trump has alienated too many groups of people - women, Latinos, African-Americans - to beat Clinton in a general election.
