MOSCOW — Given the blanket coverage on Russia’s main state-run new channels on Tuesday, it often seemed that the United States presidential election was actually happening here.

Hillary Clinton and Donald J. Trump casting their ballots warranted attention, while correspondents stationed at the polls where both contenders voted weighed in repeatedly, though news was pretty thin. Rossiya 24, the main cable news channel, promised live coverage starting at 1 a.m. Moscow time on Wednesday morning, still late afternoon on the Eastern Seaboard of the United States.

The blanket coverage had led to more than a little grumbling that the Kremlin-managed news media was devoting more time and energy to the American elections than it paid to a national parliamentary vote in Russia less than two months ago.

“Correct me if I am wrong, but this has not happened for any elections in Russia,” Dmitry Gudkov, an opposition politician who lost his seat in part because nongovernment candidates got virtually zero television coverage, wrote on Facebook.
