Michigan's March 8 primary will be here soon.

As candidates from both parties scramble to make their big push for delegates and votes, here is a map and database of all Michigan donations to the official presidential campaigns for last year.

This data does not include donations made to the various "SuperPACs" which have no financial limit set, and do not require a donor's identity.

Donation Map:

The map above plots all donations of $1,000 or made from Michigan donors in 2015, to all candidates still in the race, as well as Jeb Bush, who recently dropped out.

The map was launched with all donations above $1,000 but you can isolate by payment bracket using the "Visible Layers" window in the upper-right corner.

Donations Database:

Although the map breaks out the highest donation amounts, there have been many thousand more donations made to the campaigns. The database below allows you to search by candidate, city, and/or last name of the person who donated as little as $1 and as much as $10,000.

Total sums filed are a bit misleading since the candidates announced their runs at different times and therefore some started collecting money earlier than others. However, there are some interesting facts that can be pulled from the 15,000-plus filed entries:

For the year 2015, according to the quarterly filings of all the candidates who are running for president, Michigan donations brought in more than $4 million total dollars.

Bush brought in the most

Republican Jeb Bush brought in the most money from Michigan, with more than $980,000 dollars. Bush also finished 2015 the strongest of all candidates, filing more than $523,000 worth of donations from October to the end of 2015.

Clinton finished a close second

Hillary Clinton brought in more than $950,000 to finish a close second overall, and the top Democratic donation earner by almost $800,000 more. Bernie Sanders brought in just a little more than $191,000 from Michigan donors.

Republican Donald Trump, who has touted the self-funding aspects of his campaign, brought in the least amount of money from Michigan at $22,500.

Order by money received:

Jeb Bush (R): $975,760

Hillary Clinton (D): $950,373

Ben Carson (R): $794,217

Marco Rubio (R): $574,200

Ted Cruz (R) : $437,558

John Kasich (R): $226,292

Bernie Sanders (D): $191,313

Donald Trump (R): $22,550

On a per-donation basis, Republicans brought in the big money.

The top 17 donations for 2015 all exceeded $3,000, and all went to various GOP candidates. Ted Cruz had the single-highest filed donation with $10,400 from Brighton. The single-highest amount given to Democrats was $2,700; both Clinton and Sanders received dozens of donations in that amount.

Leading money makers by major cities:

Donations spread across the state and, as the map shows, there's no clear dominating candidate in any one market. That said, here's a list of the top money-earners by major cities in Michigan.
