When congressional Democrats figured they’d tie up President Trump in years worth of investigations into the Russia collusion hoax, whose interest, exactly, were they working on behalf of?

Surely they saw no political benefit for themselves in kicking up a cloud of suspicion, day in and day out, through the 2018 midterm season. They couldn’t have possibly seen an electoral advantage in the endless calls for impeachment. I'm sure it was all an altruistic, public-spirited effort aimed solely at getting to the truth about allegations of foreign interference in the 2016 election.

Yeah, right. Almost every poll showed that the Russia investigations ranked dead last among voter concerns. The whole point of Democrats egging on the special counsel, while conducting their own investigations, was to hamstring Trump’s presidency. And then, after the special counsel produced its report without having found any collusion, House Democrats called for yet more investigations.

But when President Trump asked the leader of Ukraine to continue looking into whether there was any corruption involved with the 2016 election and Joe Biden on his country’s behalf, Democrats and the national media put on a straight face and accused him of ... looking out for his own political interests!

The Washington Post on Wednesday said that Trump’s overtures to Ukraine fit into “a broader pattern of using both executive authority and high-ranking officials in his administration to advance his personal or political interests.”

But even assuming that would serve Trump's own political interests, why have the media determined off the bat that it doesn’t serve the public interest as well? Is it not important that we know more information about the 2016 election and what role Ukrainians might have played? Or does our interest in 2016 only go so far as the tweets and memes that Russian agents put on Facebook?

Is it not also important that we know more information about a former vice president, now a candidate for president, and whether he may have used his office to protect the overseas financial interests of his own son? The fact that this potentially implicates Biden, who happens to be running for the Democratic nomination, doesn’t put the subject off limits.

Democrats can't pretend that their own politically motivated investigations are just their constitutional duty, whereas Trump's merit impeachment, the damned traitor! Whatever his motives, Trump brought up legitimate questions about corruption in his brief conversation with Ukraine's president. Maybe Trump’s conversation with Ukraine was meant to advance his personal interest, but it served the public’s interest, too.

Democrats can’t seriously say that Trump did anything worse than their endless and ultimately worthless Russia probes.
