A former TV journalist is barred from standing by officials due to "mistakes" on her application form.
Independent politician Yekaterina Duntsova wanted to run on a platform to end the war with Ukraine.
But the electoral commission voted unanimously to reject her candidacy three days after her application, citing 100 "mistakes" on her form.
Ms Duntsova said she would appeal the decision at the Supreme Court.
The commission said 29 people have so far filed to run for the presidency. But after today's decision, Mr Putin remains the only candidate to be able to register as a candidate.
Reporter: "Mr. Putin, how is it possible that you got 132% of the vote?"
Putin: "It is merely the byproduct of our superiour domestic mathematical sciences. The numbers are simply greater than the ones produced by foreign-made axioms. Do think of all of the great achievements our mathematicians have done over centuries, such as proving the Poincaré conjecture."
Reporter: (gasp) "Your ballot results were tabulated by Grigori Perelman?"
Putin: "No, we looked at his qualifications but we figured he was out of our reach, unfortunately. We had the results tabulated by some other weird mathematician with a massive case of cabin fever. We saved a lot of taxpayer money this way."
You see, only 39% of the population voted. 95% of the people who voted, voted for Putin. So if you extrapolate that out to the entire population, you get 37% + 95% = 132%. With math like that you can't lose!
