"Republican Millennial." I might have worn such a title with a semblance of pride just a few years ago, back when Republicans were the party of Mitt Romney and Paul Ryan. Today, I, like many millennials, cannot swallow the following syllogism: The Republican Party is the party that best represents my beliefs. The Republican Party has chosen Donald Trump as the candidate that best represents its beliefs; thus, Donald Trump is the candidate that best represents my beliefs.

For myself, and numerous – dare I say a majority – of other conservative millennials, that syllogism is frightening. Trump does not represent our beliefs; however, whatever qualms one may have with the primary system aside, it has yielded Trump as the candidate most representative of the beliefs of the Republican Party, which suggests that the fault lies in the first part of the syllogism. Perhaps the Republican Party no longer represents me.

Trump has ostracized Republican millennials because his platform and strategies represent the antithesis of the political preferences that result from three characteristics of millennials writ large – the first ideological, the second dispositional and the last economic.

We millennials are often portrayed as self-absorbed, epitomizing the "it's-all-about-me" attitude commonly invoked to caricature my generation. To say there is no truth to this would be disingenuous; from marriage to the job market, it appears that millennials are increasingly individualistic.

That said, the political derivative of this individualism is less obvious, but nonetheless important: Republican millennials are headed towards classical liberalism ideologically. To the Republican millennial, whom you marry and which bathroom you use seems nonsensically irrelevant when compared to the size and wastefulness of government. Trump's policy stances on such marginal issues, opaque as they are, fail to belie what he stands for in the mind of millennials: a statist, an authoritarian and a strong man – the incarnate ideological opposite of the millennial.

The average millennial has assuredly been told at least once that they were "babied" growing up and are overly concerned with politically correct niceties and others' feelings. While potentially truthful, truer still is the fact that we are more relational and better connected to others than any generation in history, resulting in widespread unease with hateful, nativist vitriol like that often spouted by Trump. Technological advancement rendered our media as social as our generation, which together accentuated our connectedness.

Analogous to the "Erasmus generation" in Europe, ours is the study-abroad generation, and when we think of "Mexican," it is more likely that a friend comes to mind than Trump's caricature of a rapist. To the generation that learned to manipulate VPNs just to access Facebook on school Wi-Fi, the notion that a physical wall can keep out illegal immigrants is laughable, and the virulence behind the proposal is all the more off-putting.

Finally, political economy will factor into the Republican millennials' unease with Trump: He lobbies almost exclusively for trade policies that will harm an increasing number of us. Millennials are the most educated generation in history, with a college degree and a career where you can make an "impact" becoming staples in the millennial's life goals. These characteristics combined with our penchant for e-commerce are easily plugged into your standard international trade model to yield the conclusion that globalization has largely and will continue to help U.S. millennials. Trade in the case of the U.S. is most likely to affect low-skilled workers, while facilitating consumption, both of which point toward a millennial generation preferentially tailored for globalism and adverse to protectionism.

In short, one would be hard-pressed to find a millennial who has lost a job as a coal miner due to globalization, but equally hard-pressed to find one who would not revolt at the horror of higher prices for their Amazon-delivered groceries that Trump's protectionist promises would bring.

These three characteristics are by no means the only reasons for which Republican millennials are aghast vis-à-vis Trump's ascent; they are but an amalgamation of some key demographic fissures that will make the millennial Republican even more likely to find Trump unsupportable.

Why does this matter? The youth vote was a primordial building block of Obama's success, and millennials – now the largest generation in the country – will be no less integral in 2016. Beyond 2016, millennials are key to determining the future of the GOP. With millennials already being disproportionately liberal, Republicans can do more than just lose the 2016 election with how they embrace Trump – they can ostracize Republican millennials and undermine their voter base for years to come.
