In some cases, they ran in districts that were already heavily Republican, often due to gerrymandering. They won because any Republican would have won.

If other Republicans ran in the primaries, they won the primary by exciting the primary voting base. Far fewer people vote in primaries, and they tend to be engaged in hype, and MAGA is all hype based propaganda based on fear and anger. That excites Republican primary voters.

The few that defeated incumbent Republicans did so through the hate and fear angle, because it works. It is a successful fascist playbook, as shown throughout history.

So basically they mostly won for the same reason Trump won in 2016, fascist propaganda stoking fear. They promised to solve all the problems they made up about the groups they blamed.

The whole Ohio immigrants eating pets is just the same thing, dialed up to 11.

Much of USA treats their leaders team with the same reverence and loyalty they treat sports teams even if they are consistently ~~shitty~~ poopy.

Some ran unopposed.

Systematic capture. They planned it.

They believe they are living in a godless country. Liberals are out to destroy America with their evil atheist ways. They believe liberals are destroying traditional family values. They believe liberals want open borders so all the immigrants will vote for them. They believe those immigrants are all gang members just waiting to kill God fearing Christians. They believe this is a Christian country. They believe abortion is murder. Finally, they believe Trump is the only one who can save the country.

The real, possibly main answer is largely because many people, especially young people, do not vote in large enough numbers to stop them.

There's also stuff like gerrymandering that help parties in power stay in power when they get to draw the district lines but I would argue that poor turnout is what makes the biggest difference.

Hurt people. And yeah a lot of

Conservatives typically win by promising what they will not do vs. what they will do. (At least the true conservatives do. Not all Republicans are conservative though)

The way politics works now is that MAGA tries to reenact the Handmaid's Tale and/or sell the world to disaster capitalists while doing nothing to actually govern, Democrats try to play it cool and actually govern sometimes, and dark money gets poured into elections to make everything even murkier.

The same way all regime whores get into the office... Donor money and captured political process.

While plebs fighting culture wars, the parasite class is executing a class war!

They promised to be "not biden", and lemmings ate the fish like dynamite.

See, that phrase didn't make sense, but it doesn't need to. Politics for these people isn't about policy, or logic, or even country. It's about "if I win, you lose, so fuck you!".

And that's how we got here.

Citizens United. In 2001, corporations were suddenly allowed to donate an unlimited amount of money to political campaigns. Campaign donations were deemed a form of expression protected by the first ammendment. The entrenched far-right republicans were suddenly being outspent by even further right people from out of nowhere, unseating many of them. The game for both parties then became how much corporate donation can you attract, and for Republicans, they found the further right you go the more votes you get. So republican nominees could have standards or keep their job, not both. The ones that were the far-right were still professional legislators, genuinely believing conservativism is in society's best interest, and many of them tried to resist, like McCain and Romney. The new far-right ones are professional shills in it for personal gain. The old ones are greedy cowards who know better. The Republicans have slid right at lightspeed ever since Citizens United.
