The Reagan era conservatism gave out of gas in the 2nd term of the Bush Administration. It was a good run with the small government/libertarians/strong national defense/evangelical alliance lasting approximately 30 years (1975-2005). The Press in the early to mid 2000s transitioned from being simply biased towards the Dems to being Democratic activists - opening rooting for the Dems and vocally opposing the Rs. This caused the conservatives to retreat to Fox News and Rush and talk radio. Then, the Great Recession ushered in the Obama "we're all socialists" era.
Obama turned the party hard left, especially in his 2nd term. He was worshiped by the boot licking press. The reaction on the right was the Tea Party - which was a populist movement emphasizing the debt Obama was running up. The two R Presidential candidates of this era - McCain and Romney - simply wouldn't fight back and respond to the activist Press and increasingly leftist Dems - choosing to play by the old rules. The activists gained power in the Dem party and were pushing the boundaries on the cultural front (what we now call "woke").
Then comes the 2016 primary. Most of the candidates were pretty normal conservatives. Early on, I aligned myself with Rubio thinking the country needed some new conservative blood. Plus, he was marginally associated with the Tea Party. Trump comes in like a bull dozer and does his Trump thing. I didn't initially support him because I didn't think there was anyway in Hell he could win a general election. As time went by, many if not most traditional conservatives supported him because "at least he fought back" with the Press and the Dems unlike McCain and Romney. The unrelenting attacks by the left only caused more Rs to line up behind him as "their guy." Trump appealed to blue collar types the way Romney wing of the R party never could.
As everyone notes, Trump is not a conservative. The Rs have essentially leased Trump to disrupt and take on the Dems - who were growing more left and more woke during and after his term. A lot of Trump support from traditional Rs is "I can't stand those nut cases" and Trump's at least taking them on. Plus, Trump does have some conservative views:
Law and order and support for the police.
He's now embracing a smaller leaner government with DOGE - which he didn't support during his first term.
Tough on China.
Pro Life
Strong borders
Supporter of religious institutions
Strong ally of Israel
Anti - woke madness
Equal - not equitable - opportunities for all
Tariffs and foreign policy is where he strongly veers from the Reagan era. But, on these issues, he has a point. Free trade is great but not always - especially when other countries to not reciprocate. Strong national defense is fine until it evolves into Neocon and endless war foreign policy.
All the crazy stuff about Trump conservatives don't always like, but generally accept, is simply part of the package. We don't see Trump as a "threat to democracy" or that we're headed to a dictatorship. After he completes this glorious term, he'll be gone and parts of the MAGA movement will remain but there won't be another Trump. He's a unicorn. No other politician can get away with what he does so they won't try. Some of the hard core MAGA will stop supporting Rs and return to not voting.
In short, I really haven't changed my conservative principles, I'm just willing to allow Trump to do his thing as the Disrupter in Chief since the Dems went so far crazy and his methods often get things done.
Remember, you asked my opinion.
