1) The requirement to have a passport, which costs money, is a poll tax and therefore will make poor Americans less likely to be able to vote. Due to past and present racism in the US, especially southern states, minorities are especially likely to be poor.
2) Requiring the same name on their ID as on the person's birth certificate will make a lot of people lose voting rights, especially married women. This also goes for a lot of people who were born in a non-English majority country. In summary, a lot of women and minorities.
3) This first blow against the voting rights act will make it legal for Republicans to gerrymander away minorities' power. Previously, it ensured that gerrymandering couldn't be used to dilute minorities' power; For example, if a state was 30% black, states had to give black populations 30% district representation. Now, their power can be diluted by the white majority.
4) The attack on the voting rights act shows that they are willing and able to completely repeal it. They can and they will completely take it away, allowing Republican states to deny minorities the right to vote. Since minorities heavily lean Democrat, this allows Republicans to essentially steal elections even more so than they already do.
5) All the usual election stealing that Republicans do, such as depriving Dem-majority districts of polling places, attacking mail-in voting so only in-person voting is doable, disallowing people from sharing water to people in line to vote so it's physically exhausting to go vote....and of course simply doing things without a vote, such as Texas' gerrymandering, or even completely ignoring the results of votes when they go the way they don't like (such as abortion rights voting).
