Razi might be wrong because the percentage of votes is related to the number of votes. And the percentage just indicates the ratio, not the actual number.
For example, let's assume that voters cast exactly 1000 votes last year. Since this political party received 65 percent of the votes last year, it received 650 out of 1000 votes.
Let's assume that voters cast 100 votes in the elections this year. In this case, this political party, which received 70 percent of the vote, received 70 votes out of 100 this year.
In this scenario, although the party's percentage of votes increased, the number of votes decreased.
