No.
He had an enemy to fight
He made sure the rich backed him, such as big Oil. Jailed those who did not
He put certain people loyal to him in high positions of power

'Superb candidate' for presidency On 9 August 1999, an ailing Yeltsin sacked his prime minister, replacing him with a little-known 46-year-old protege who would see through reforms ahead of presidential elections in 2000. Yeltsin was by now in need of a successor. "Putin had shown himself to be a liberal and a democrat, who wanted to continue market reforms," said Valentin Yumashev, who told Yeltsin he would make a "superb candidate".
As Yeltsin's presidency faded away, Moscow was hit by a series of deadly but unexplained bombings. Vladimir Putin responded with a full-scale land offensive to recapture the mainly Muslim Russian republic of Chechnya from separatist rebels. His popularity soared and on 31 December 1999 he was appointed acting president, winning his first presidential term three months later. Thousands of civilians died in the Chechen campaign and, as he often does, Vladimir Putin used crude language to describe how he would wipe out the rebels "even in the toilet". The capital Grozny was devastated; Russia's leader had his victory.
Four years later, Chechen rebels took 1,000 hostages, most of them children, at a school in Beslan, North Ossetia. When Russian special forces stormed the building, 330 people died. It later emerged that Russia had intelligence of a planned attack but had failed to act. The first years of the Putin presidency were both bloody and turbulent, but the Russian economy was doing well, buoyed by high oil prices. He won public support for taking on the billionaire oligarchs who had run rife in Russia in the 1990s. Summoning them to the Kremlin, he said they could keep their money as long as they kept out of politics and backed him. He acted fast against those who didn't, such as Russia's then-wealthiest man Mikhail Khodorkovsky, who was arrested at gunpoint and jailed in Siberia.
Trump's plan coincide to accomplish these same things.
Your hypothetical protests against Trump will never happen because if that many people refuse him he could not win the election. If he wins that has meaning.
