"It is unlikely Yanukovich won. If he did, his government made it impossible to determine"

Bob Schaffer's quote suggests that it is unlikely that previous Ukrainian President Viktor Yanukovich won the election. If he did, his federal government made it difficult to identify the result due to their actions. This could mean that the government took actions to prevent a fair and accurate election, such as tampering with the ballot procedure or controling the outcomes. It could also indicate that the federal government made it hard to access the results, or that the outcomes were not released in a prompt way. This quote implies that Yanukovich's federal government was not transparent and did not enable a free and fair election. It also recommends that the results of the election might not be trusted, as it is impossible to determine the outcome. This quote highlights the value of a transparent and reasonable election process, and the requirement for governments to guarantee that the results are accessible and accurate.
