If by "stop the democrats from winning again" you mean "only allowing citizens to vote, and requiring them to have ID", or "investigating and prosecuting election fraud" - then yes, absolutely. It will be, hopefully, much harder for Democrats to win.
Democrats have not had a populist mandate for 20+ years. That's been a big part of the problem. RFK Jr and Tulsi being rejected by the Democrat elite is perfect example of this. They are not the populist party they once were, and are instead the tyrannical party - just like the Republicans used to be. Tyrant and populist flip back and forth from administration to administration, it's not a D or R thing. But for the past 20 years, it's been the Ds. It's become a very small in-group of select elites who like to pretend they're populist. They've willfully embraced mediocre and even incompetent people on ideological grounds (DEI and otherwise) and the results have been disastrous for both the party and the country.
I'm hopeful that Trump's got Musk and his "Dept of Gov't Efficiency" and that he's enlisted the help of Ron Paul, of all people, to help with those efforts. There's nobody who understands the topic better. I'm hopeful that RFK Jr will do something for the health epidemic in this country by cracking down on toxic seed oils and sugar, and subsidization of unhealthy diet choices in general. I'm hopeful for a lot of things, but realistically it probably won't change much - there's a lot of bureaucracy which will resist all of those efforts, and Trump's neocon pics last term don't leave much room for hope.
We will see. Nobody expected the basement-hiding geriatric dementia patient of Joe Biden to win 2020, so stranger things have happened.
