Ohio, the Buckeye State, may again be instructive on the Presidential Election of 2020, as it has been 45 out of 54 times in the past, and only twice on the losing side since 1900–1944 and 1960!
No Republican President has won the White House without winning Ohio.
Ohio is 34th largest of the 50 states in land area; 10th most densely populated; and seventh most populous; and it has been losing electoral votes steadily over the decades, as the Sun Belt states have grown larger in population.
But it still matters greatly, and recent polls indicate Joe Biden taking a lead in Ohio over Donald Trump.
As I wrote on this blog on September 15, 2018, Ohio historically has been the most predictable state in the Electoral College results, followed by Illinois, Missouri, Nevada, and New Mexico.
If Donald Trump cannot win Ohio, there is no path for him to win the Presidency for a second term in 2020. The public opinion polls as I write, indicate troubles for Trump also in Iowa, Michigan, Wisconsin, Pennsylvania, and Minnesota, so the Midwest heartland is not for him, as things stand now.
