Should all states implement same-day voter registration? What are the potential barriers to the widespread adoption of this practice?

If the goal is to make electoral participation easier, then, yes, we should implement same-day voter registration. We have systems in place that allow us to check residency and eligibility credentials. Same-day registration removes a point of friction in the process of voting. The largest barrier to adopting any expansion or easing any part of the process of registering to vote is that the election and re-election prospects of a fair number of candidates and elected officials benefit from rules and procedures that increase the difficulty of registering to vote and casting a ballot.

How common is voter fraud in the United States? What impact does it have on state and federal elections?

If by voter fraud you mean the intentional act of casting an illegitimate ballot, then voter fraud is extremely rare in the United States, and the impact is basically null at the state and federal levels. Claims of rampant voter fraud in America are unsubstantiated by evidence that has been presented in courts and passed through rigorous peer-review processes. Despite having fifty different systems for administering elections, we have a remarkably robust set of institutions and regulations that keep the integrity of our electoral systems. On the other hand, if by voter fraud you mean the intentional act of suppressing voter participation, then rules like Voter ID laws, felony disenfranchisement, the deliberate malapportionment of voting machines, poll workers, precinct sites, and other resources, the refusal to allow vote-by-mail to all eligible voters during a pandemic, among other practices, constitute a more common and widespread version of voter fraud.
