The headline claims"voters out in force"
The numbers tell us otherwise- And we see these numbers in Canada and the US
They are the numbers of disillusionment, disgust, distrust and disdain for the political classes

"Turnout across the country was reported at over 38 percent after seven hours of voting"

That's right after seven hours of voting, just a smidgen over 38 percent of the population has turned out....

The Ukraine also changed the rules of the election concerning minimum turnout-

 No minimum turnout is required to validate the outcome but if no candidate wins more than 50 percent, a second round run-off will be held June 15.

So if 1% of the populace vote for a candidate, it's valid

Good article- Is Ukraine ready to vote?

The answer is NO. Clearly. They aren't ready to vote. Many residents don't want to vote.

For Ukraine to have a successful election, the DECs and PECs must function effectively. PECs oversee the act of voting, from checking voter identification and distributing ballots, to physically tallying the results after the polls close. Well-trained and fully staffed polling station commissions are a crucial component of a credible election. DECs compile PEC results and adjudicate disputes; unstable staffing could make the completion of these tasks more difficult. These challenges are even more acute given instability in many of Ukraine’s regions.

DECs were initially formed on April 14 and PECs were announced on May 6. The establishment of Ukraine’s election infrastructure has been impeded in many ways. Russia’s annexation of Crimea effectively closed 12 DECs (1-10 and 224-225). For the remaining 213 DECs, personnel assignments have been unstable, with officials joining and leaving the commissions over the past few weeks. 

Electoral commission personnel changes are widespread between the initial registration phase and election day. Membership on DECs has changed both inside and outside of areas embroiled in conflict.

 PECs have experienced a different challenge; instead of unstable personnel, candidates have not supplied enough representatives to complete the staffing requirements. The law initially indicated that each PEC should minimally have 12 members, allocated by candidates. This minimum requirement was lowered to nine on May 6, likely due to significant challenges of finding enough willing participants.

 At the deadline for PEC staffing, 191 constituencies had announced the appointment of 352,238 total staff members for their polling stations. Over 38,000 of these staff members were directly appointed by DECs rather than by the candidates. Twenty-two DECs provided no information about PEC staffing at all, and most of these districts are located in Donetsk. The map below illustrates the problem of polling station staffing.

This is about all the information I can find on the so called huge turnout in Ukraine

Voter turnout in presidential elections in Ukraine is now 38.53%

Kiev. Voter turnout in the presidential elections in Ukraine was 38.53% by 3 pm local time, RIA Novosti reported, citing data from the Central Electoral Commission of the Eastern European country.
The biggest voter turnout was registered in Lviv Oblast, 52.15%, and the lowest in-Kharkiv-24.05%.

Tell me how it is that the very  well attended referendums in Donetsk and Lugansk, not to forget Crimea, can be declared illegitimate by the western/nato tryannies? It does look as if the Ukraine elections, more appropriately, fits the illegitimate label...
