Well you're not wrong, people DO move to some of these places because of their reputation so they can feel like they're among like minded individuals, but I maintain my position. Remember, when this all of this over only 4-6% will still be lost and liberal. Ergo, unless you have ALL OF THEM congregate in like, 4 cities. There won't be enough of them collectively turn any major city blue, based on population size and percentages.

As for the college thing, I don't know what to tell you. The total enrollment numbers for every college in the US is public info, the 20K number I threw out applies to all but the largest colleges, but for argument's sake let's use the literal largest college in the country, Texas A&M.

Texas A&M, as of now, has 72,982 students. College Station, the city in which the college lies, has a population of 120,511. Brazos county, the county the college lies in, has a population of 233,849.

So using basic math, the student population of Texas A&M makes up 60.56% of the city's population, but only 31.2% of the counties population. So on the surface, yes you appear to be right that this city would be "blue" based on it's massive student population (not that they should be voting in a place where they don't live full time and only go to school, but that's a different point). However, this assumes EVERYONE who goes to Texas A&M is a lefty. Which obviously isn't true.

Let's assume a low end estimate for conservative students of 80-20% in favor of a left wing tilt, and a high end of 65-35% with a left wing tilt. Using the low end estimate, the leftist college students make up 48.45% of the city's population and 24.96% of the county's population. So already we're now at the point where they're no longer enough to turn the city or county blue by themselves.

Going further and using the high end estimate we find that they make up 39.36% of the city's population, and 20.29% of the county's population. And I'm using rather conservative estimates here when you consider that we now have proof that colleges lie and inflate their student population numbers to gain more funding (like what's been revealed happens in california).

So with all that in mind, and keeping in mind this is the literal largest college and college town in the country, it's reasonable to say that most college towns aren't blue without cheating either.

Also, just a little side note. The number of college AGE people has increased, but the number of UNIVERSITY students has decreased. The numbers you usually see are inflated by including trade schools and apprenticeship mediators. Universities are dying off, and in the last few years, many have actually closed permanently due to lack of funding and subpar enrollment rates.
