Gerrymandering has no effect on votes for president or senate, and ranked choice/range voting has no impact on gerrymandering. To eliminate gerrymandering you'd need to have an at-large/seat based voting system instead of district based. In other words - instead of voting for a representative, you'd vote for a party - and the party would then fill the seats they won at their discretion. Another option is multi-member districts which is a 'softer' version of the same idea.
