He and the other spelling has its supporters fervently defend their point of view. In the Russian language there are words that can be pronounced in different ways (for example, choosing the stressed syllable), and some debaters are trying to find a compromise and to prove that the word "come" can also exist in two versions. This was actually possible, but only up to 1956. Look in the dictionary D. N. Ushakov.

The most common misconceptions about the reasons why, supposedly, you need to write "come": "the Word "go" spelled with a "d", so "come" is the right option," "the word verification - go", "I always wrote, and I think that's right." Also often say that both options can be used as search engines on the Internet give almost identical results for both forms of the verb.
