Donald Trump thinks he'll walk away with five wins in primaries tomorrow, picking up three in the mid-Atlantic – in Pennsylvania, Maryland and Delaware – along with the New England states of Rhode Island and Connecticut.

He told supporters yesterday in Hagerstown, Maryland that he was looking forward to competing against Democratic frontrunner Hillary Clinton, who looks poised to take her party's nomination.

'An election between crooked Hillary and wonderful Donald,' Trump said, giving himself a new nickname, according to the Hill. 'It'll be the biggest, most incredible vote-getting election in the history of our country.'

Donald Trump is predicting wins in all five states voting tomorrow - Pennsylvania, Delaware, Maryland, Rhode Island and Connecticut

Yesterday as he campaign in Hagerstown, Maryland he made up a new nickname for himself - 'wonderful Donald' - and told the crowd he was excited about running against 'crooked Hillary' in the general election

But Trump needs to wrap up the Republican nomination first.

He made the pitch to his own voters in Maryland yesterday explaining, 'Trump has millions of votes more by that time because you look Tuesday, it looks like five,' he said, suggesting the popular vote should be taken into account when deciding who should be the GOP nominee.

'I don't know, but I believe in polls,' he continued, according to the Hill.

'So let's say we win five. We win all five states, we pick up a lot,' Trump added.

The polls do show encouraging news for The Donald.

Public Policy Polling came out with surveys this morning from three states that vote tomorrow.

In Rhode Island, Trump is 38 points ahead, with 61 percent support, compared to Ohio Gov. John Kasich's 23 percent and Texas Sen. Ted Cruz's 13 percent.

In Connecticut, Trump is 34 points out in front, receiving 59 percent from likely Republican voters. Kasich again comes in second with 25 percent, and Cruz again receives 13 percent support.

The way Connecticut Republicans allocate their delegates is that each of the five congressional districts gets three delegates, given to the winner of that district, and then there are 13 at-large delegates, which will go to Trump if he indeed wins the entire state with over 51 percent.

In Pennsylvania, which has complicated delegates rules too, Trump also leads.

The PPP poll has him 26 points ahead, with 51 percent of Pennsylvania Republicans supporting The Donald versus 25 percent for Cruz and 22 percent for Kasich.

Additionally, a PPP poll that came out last Tuesday that surveyed Maryland Republicans had Trump 14 points ahead in that state.

And a Gravis poll from last Wednesday showed Trump 37 points ahead in Delaware.

Trump will need commanding victories in the rest of the presidential primaries to pick up the 1,237 delegates needed to clinch the GOP nomination on the first ballot of the Republican National Convention, when delegates are 'bound' to the winners of their states.

If he doesn't meet that threshold, it's likely the nomination will be wrestled away from him on subsequent ballots through a convention floor fight.

Last night both Cruz and Kasich announced that they planned to focus their resources on particular states – Cruz in Indiana and Kasich in Oregon and New Mexico, to prevent Trump from picking up enough delegates to win the nomination.

If their efforts are successful, Trump suggested he wouldn't be gracious in defeat, as he mocked the conciliatory concession speeches delivered by other candidates.

'They fight like hell for six months, and they're saying horrible things, the worst things you can imagine,' Trump said. 'And then one of them loses, one of them wins. And the one who loses says, "I just want to congratulate my opponent. He is a brilliant man, he'll be a great governor or president or whatever."'

'I'm not sure you're ever going to see me there,' Trump said in Maryland, according to Business Insider.

'I don't think I'm going to lose, but if I do, I don't think you're ever going to see me again, folks, I think I'll go to Turnberry and play golf or something.'

Trump, however, has vowed to fight on.

'I really want to fight Hillary,' Trump said yesterday. 'I don't know if she'll be easier or harder, but that's the one I want to beat.'

Trump slammed Clinton's rival too, telling his audience that Vermont Sen. Bernie Sanders, a democratic socialist, wants to take '100 percent of what you make.'
