/r/politics, Reddit in general, is so soaked in Liberalism it's completely oblivious to the most profound bubbling and reformation of the Republican party in modern history.
Anywhere dominated by youth under 30 is typically soaked in liberalism. The vast majority of that demographic is ideologically liberal or left-leaning at the moment. The metamorphosis of the Republican Party is not new; it has changed faces several times over the past 4 decades. This reformation and bubbling is neither objectively bad or good, but it is definitely expected; in response to rapid changes among the electorate, the Republican Party is shifting. This is not a new political phenomenon, and this is not unprecedented.
Record turnout, Trump is expanding the tent and steering the GOP away from the 'neocon' tag of the 90's and the 'teaparty' tag of the 00's. He's bringing back what was once (allegedly) the core of the party; economy and fiscal conservatism and an 'America First' attitude (Liberals, please imagine for a second that it's actually not a bad thing to put your country first).
Donald Trump has not consolidated control of the party or dominated its politics. He still does not control all of the party's voter base. We will see if it actually shrinks or grows come November of this year. Core of the party is based on who votes for it. It changes platform and rhetoric as it gets a feel for what its base wants as a whole. Fiscal conservatism has always been a part of the Republican core. That is not new either. The 'America First' attitude is not contrary to liberalism. America always comes first in most Americans' decisions when they vote because we live here, and the decisions we make in elections affect us most. I hate this misconception that being liberal somehow equates to being anti-America because most people in America are not against it, but many do believe, including conservatives, that we could do better as a country.
Perhaps the most important aspect to all of this is that Trump is accomplishing all of this WITHOUT the backing of religion. The ultra-right religious demographic is going with Cruz, and losing. This can put the entire Republican party on a new path that will last for decades.
The religious right is not the sole driver of success in the race for the Republican nomination or the presidency. If he does well without the support of evangelical voters, it is not astronomically profound. While many people do factor their religion into their decision, most people do not cast their votes with a Bible in their hands and take a more holistic approach to the candidates and the policies in question. You can definitely win the Republican nomination without the evangelicals in your pocket. They are outnumbered, and they have been dying down over the past decade. While religion is certainly important to some candidates, I'm sure, it's not, nor has it ever been, the main pillar of the Republican Party.
BUT SADLY, all of the alleged Progressives can do is plug their ears and make completely baseless and unfounded and unproductive claims of 'racism' and 'misogyny' and 'drumpf' while phonebanking for and donating to a campaign that has been mathematically out of the race for the past 2 months.
If you want to talk "mathematically out of the race," go talk to Kasich's campaign. I'm sure they'd love to chat. Anyway, Ted Cruz and Bernie Sanders both trail the frontrunners by a close number of delegates, but nobody has said that Cruz is a mathematical impossibility. Anyway, would you rather have that nobody even put up a fight against Clinton on the Democratic side over someone throwing her out the door early? The opposite side is no greener, with completely baseless and unfounded and unproductive claims of 'communism' and 'immorality' and 'welfare state'.
