Yes , you’re right, Putin’s a career politician like Feinstein, McConnell et al. Like FDR.
George Washington could have been president for life, or even King. He knew not too.
Only FDR broke with Washington’s example.
We put in two term limit after that.
Putin faced term limit so his puppet was official president, then did away with term limits to be president for life.
Like all career politicians Putin has become unimaginably wealthy, perhaps being the wealthiest man on Earth.
He makes even Feinstein or Clintons look like pikers when it comes to career politicians getting wealthy off graft.
Presidential term limits for Russia, are set by the Russian Constitution, like they are in the U.S. Consitution. Putin recommended a public referendum to change the number of Presidential terms that can be served in Russia. It was passed by a national vote in 2020. The people of Russia voted to change their country's Presidential term limits, and exempt Putin from presidential term limits until 2036. But of course, there's no guarantee that there wasn't any ballot fraud during that 2020 public vote, which is no different than what goes on here.
In the U.S., Democrats maliciously impeach Republican Presidents to end their term of office, or steal elections, but I'm sure that crap goes on in Russia too, and in plenty of other countries around the globe. What I haven't seen much of in other countries is the opposing political party using law fare to bankrupt, and take down their opposition, as it is used in this country.
