On abortion: term-limits have been the principal means whereby opponents of Abortion unable to make it illegal, have sought to impose such strict limits as to make it almost impossible or at least reduce the number of abortions carried out in the state; but there are also arguments about abortion which go beyond the basic argument about conception, to consider the medical arguments when dealing with a foetus that is in some way damaged and beyond hope of life, or when the mother's life is at risk with a continued pregnancy. There is also the issue of pregnancy caused by rape, and these moral rather than medical issues have also divided legislators.
A Conservative on the Supreme Court may take the extreme view that a woman must carry a pregnancy to full term even if she was raped, be it by her father, her brother or a stranger, but others on the Court would object and unable to reach a conclusion, and thus term limits -rather than the repeal of Roe-vs-Wade would be seen as a 'compromise solution' that States could then continue to impose. The point would be that having a new Conservative on the Court would not necessarily tilt the judgements in favour of the Christian Fundamentalists, but would result in a compromise that protects the status quo to nobody's satisfaction, unless in conservative States the voters opt for change.
I don't really understand how district boundaries in the US are drawn, and that would seem to me to be the problem for the Supreme Court as well. In the UK constituency boundaries (recently reviewed to reduce the number of seats in the Commons from 650 to 600) will come into effect at the next election, and are based on a mix of size (around 72,400 in England, 69,000 in Scotland 66,000 in Northern Ireland, 56,000 in Wales) and also demographics defined by income and social class, the intention being to produce constituencies which have a reasonable mix (but often not possible in mostly rural constituencies).
An attempt to manipulate electoral rolls has been unusual in the UK but, ironically in view of the horrific fire in North Kensington -where the council has tried to re-locate poorer residents not just out of the borough but London itself (Hasting, if you can believe that!)- it happened in Westminster in the 1980s when the leader of the council, Shirley Porter, attempted to manipulate elections by moving council tenants, assumed to be Labour voters, out of marginal wards to replace them with owner-occupiers, assumed to be Tories, giving the council permanent Conservative control. It is considered the worst case of gerrymandering in recent British history.

As for voter suppression, I can understand the point about the 1965 Act needing to be updated, but I wonder on this, as well as the other two issues above, if the Supreme Court, Conservative or Liberal is always reluctant to impose a Federal judgement on a State if that would intrude on the right of the State to make its own laws. Although it would seem obvious that a balance can be found between the two, it is notable that the Supreme Court has not enforced a nationwide ban on capital punishment because each State can determine that for itself. I think voting is so crucial to an open democracy that decisions on how to register voters or remove them from the roll should probably not be the exclusive right of individual States, and that voting rights should be the same in every State, but that the procedure for voter registration should also be the same across the country.
Lastly, it is one of the peculiarities of the US that States Rights appears to produce such imbalances in justice that lead you to this astonishing statistic on capital punishment: the death penalty is on the statute of 32 States, but the death penalty itself is only performed in 2% of the counties in those States, 60% in just four states -Texas, Virginia, Oklahoma and Florida or if you prefer, 82% of executions are performed in the South, barely 1% in the Northeast-

If you are a bad boy then live in California, not Florida, definitely not Texas, or at least choose Austin, and pretend to be weird.
