So here I am on the election set as we await the vote tally from Wisconsin where the polls close in less than an hour.

Important night for the GOP.

If Donald Trump wins, he will likely get the nomination.

If he loses in Wisconsin, a much longer nominating process will kick in and Ted Cruz will pick up some steam.

Both Cruz and Trump have called for John Kasich to drop out no matter what happens tonight, but that is not likely to happen.

A Wall Street Journal editorial today says that the governor may bide his time until the convention in July, hoping he can win the nomination on delegates who defect after the first ballot.

It's all very complicated, but if Trump does not get the 1,237 delegates needed, there will be a big fight in Cleveland high noon drama.

A non-scientific poll on BillOReilly.com asked, "Should John Kasich quit the race?"

• 77% say yes
• 23% say no

Nearly 35,000 of you voted.

But if you look at it from the governor's point of view, he thinks he has a chance if the controversial Trump and the ideological Cruz do not have the delegates to win the nomination outright.

Similar situation on the Democrat side, Bernie Sanders hanging tough knowing that Hillary Clinton controls more delegates.

But Mrs. Clinton has that FBI thing that "Is It Legal?" will define for us later.

If Hillary is indicted over the email deal, Sanders believes he can win the nomination.  So why not hang on?

The Trump campaign seems to understand that their guy has to broaden his base by being more specific.

Mr. Trump now says he will stop Mexican nationals in the USA both illegal and legal from sending U.S. dollars back home if Mexico does not contribute billions to build a wall on the border.

Another controversial plan, but one that goes beyond the general statement that Mexico will pay for the wall, that I can tell you.

American voters deserve specifics in a very important election, and it looks like the Trump campaign is responding to that.

We have asked Mr. Trump to appear with us tomorrow, and I hope he will be here.

Summing up, Wisconsin matters and we'll know what the voters think in less than 60 minutes.

That's the memo.
