Donald Trump is leading the Republican presidential race in large part thanks to the South. With nearly all of the South having voted now, Trump has taken 54 percent of the delegates there.

But will that success continue as we move to more states in the West and the Midwest? The limited evidence we have so far suggests it might not. Ohio Gov. John Kasich won his home state March 15, but Trump's narrow win in Missouri put him in the delegate lead in the Midwest. Sen. Ted Cruz of Texas almost won the West, thanks to his win in the Idaho primary and lower-profile caucus states, however Trump just barely outpaced him thanks to the businessman's win in Arizona.

[Kasich wins Ohio with an eye toward a contested convention]

Trump took the lead in the Midwest because he won 25 delegates in Missouri while Kasich took none. Cruz lost narrowly and earned 15 Missouri delegates. Now Trump leads the region with 37 percent of the delegates. Kasich has 26 percent and Cruz 25 percent. Marco Rubio got less than 10 percent of the region where he had hoped to connect with a wider group of establishment and tea party voters.

Trump won by a wide margin in Florida, beating Rubio in his home state and raking in 99 delegates.

* Colorado is not holding a GOP primary election in 2016.

Most of the big contests in the Northeast are still to come, with New York and then Pennsylvania and New Jersey, but Trump has taken 48 percent of the delegates in the region so far. Kasich has taken 21 percent due to his second-place finish in New Hampshire. Cruz has won 18 percent.

Trump's win in Arizona gave him 50 percent of the delegates so far in that region. Cruz is not far behind with 44 percent. Kasich has not campaigned or drawn support there.

[Rubio’s demise marks the last gasp of the Republican reboot]

Former secretary of state Clinton’s dominance over Sen. Bernie Sanders of Vermont covers all four regions of the country if you include the party leadership “superdelegates” that are overwhelmingly favoring her. But Clinton has not done as well in the Midwest or West as she has done in the East and, especially, the South. After winning Michigan, Sanders accused her of being a regional candidate, but since then she has won Ohio, Illinois, Missouri and Arizona, and is leading the delegate race in every region.

Note: Diagrams do not include delegates in earned in U.S. territories, or unpledged delegates. Superdelegates, labeled here as unpledged delegates, are free to support any candidate for the Democratic nomination although their vote is not official until the Democratic National Convention in July. Delegate counts as of March 25.

[A good night for Trump and a better night for Clinton]

Clinton has won 68 percent of the delegates in the South, 60 percent in the Northeast, 52 percent in the Midwest and 53 percent in the West.

Hope is not completely lost for Sanders, but he has not mustered a majority of the delegates in any region despite the enthusiasm he generates among supporters. The Midwest has provided his best showing thus far, with 43 percent of the delegates.
