Using a map of how the states voted in the last 4 elections excluding the 2020 election, I have calculated
Democratic states (which I have defined as having voted blue at least 3/4 elections) amounted to 250 electoral votes
Republican states (which I have defined as having voted red at least 3/4 elections) amounted to 204 electoral votes
And the swing states amounted to the remaining 53 electoral votes
In this democrats would be more likely to win the states votes because their states accumulate the more electoral votes than republicans
