If you keep getting game overs, a good way to avoid losing the game is to avoid taking any risky actions, such as violent activity or things that get you in trouble with the law. However, if you take a risk-averse strategy and try to play things safe, this makes it more difficult to win over public opinion and win the game.
Anyway my suggestion is to repeatedly have your founder go around picking locks but NOT going into the apartments, first at housing projects, then at university apartments, then at downtown apartments, as your Security skill goes up. Once you have high security skill, go into apartments and steal stuff, but only when nobody is looking. If Conservatives get alarmed, get out of there as quickly as possible. Also you will want an armor with good Stealth for this. Tailoring skill and making your own armor is a good way to get armor with Stealth. I would start out with a Trenchcoat, then move up to a Ninja Costume once there is enough Tailoring skill and money, then move up to SEAL Stealth Armor once there is enough Tailoring skill and money. With Stealth you'll be able to get away with doing illegal stuff when people aren't looking, and then they won't be as suspicious of you as they would be towards someone without Stealth. Also build up the Disguise skill too. Also talk to lots of people about issues, max out your Persuasion. And ask lots of people out on dates, max out your Seduction. Then get your Juice up to 200 (Urban Commando) by repeatedly stealing stuff and not getting caught. If you do things right, you won't be wanted by the police for anything at all, but you'll have high levels in several important skills.
After this, you'll want to get a car, which you can either steal or buy. You'll also want a weapon small enough to conceal but scary enough to intimidate. A Combat Knife is excellent for this. Now go to places, ask Conservatives out on dates (they'll probably say yes since your Seduction's maxed out at this point), and then on the date, kidnap them. Kidnapping should work, because you have a scary weapon, and because you have a car that you can drive back to your hideout in, with the kidnap victim trapped inside the car the whole way. Attempting a kidnapping without a scary weapon or without a car is a bad idea, you want those first before you start kidnapping. Then after you get the Conservatives kidnapped, interrogate them. You'll want to wear Bondage Gear for interrogation, it makes interrogation more effective. Your Psychology skill will go up the more you kidnap and brainwash people. If you brainwash them fast enough they'll never get reported missing, and you can turn them into Sleeper agents. Once you're really good at kidnapping and brainwashing you can get a lot of high-level Conservatives as Sleepers.
Once you have lots of high-level Conservatives as Sleepers, have them Laying Low until their infiltration is above 90% or until it is September or October. If their infiltration is above 90% or if the current month is September or October, you'll want them Promoting Liberalism. Having lots of Sleepers do this will be very effective at promoting the Liberal cause. But this does not directly impact public opinion, it impacts how much influence the Liberal Crime Squad HAS on public opinion. Now you'll want to recruit a liberal Programmer with high Computer skill and have them at a different site from your Founder, and have them do nothing but Hacking. This will have a huge impact on public opinion over time, enough to win the game if you never get caught. Having the hacker be at a hideout that has a business front and an American flag flying out front will give them enough cover to avoid being caught, especially if it's just 1 hacker. Also, you'll want a Printing Press set up at the same site that has the hacker and the business front. Then whenever they get documents, you can publish them in the Liberal Guardian newspaper. This is the part that really has a huge impact on public opinion, especially because of the activities of your Sleepers Promoting Liberalism. Then because of public opinion, Congress, the Supreme Court, and the President will all eventually become Elite Liberal, along with all of the laws. And if the Conservative Crime Squad starts doing stuff, don't worry, because of your Sleepers' actions along with the documents you regularly publish in the Liberal Guardian newspaper, public opinion will be very much against the Conservative Crime Squad, and everything they do will only alienate the public against the Conservative cause and make Liberalism even MORE popular. You can try destroying and eliminating the Conservative Crime Squad if you feel like it, but if you succeed at that, they will no longer be alienating the public on a regular basis, so public opinion won't move as fast in the Liberal direction afterwards, it will probably increase the number of years it takes to Liberalize the country.
Anyway that's how you can beat the game without too much risk. And try and keep your Founder out of trouble. If your Founder ever gets in trouble for kidnapping, a good way to make this go away is to send the person you kidnapped and got reported missing and didn't become a Sleeper on a suicide mission. Just send them out unarmed someplace and have them start fighting Conservatives, and soon they'll be dead, which is good, because if you didn't get rid of them the police would come after both your founder and the person who got kidnapped, and then the person who got kidnapped would rat out your Founder and testify against them in court. Not cool, better to kill them off before they can do that, and it's best to kill them off by sending them on suicide missions. You can also kill or set free a member of the LCS if they're at your base, but that's not good, since killing them makes you lose Heart, and if you set them free they'll go to the cops and rat you out. Suicide missions are the way to go for getting rid of people in this game. The LCS is a terrorist organization, after all.
