I have to ask how did you determine that Republicans are far less educated than Democrats?
Even though this is WAY off topic, I can answer this.
Over the past 20-25 years, the college degree "party" has flipped from Republican to Democrat. 54% of undergrads say they are Democrat or "lean Democrat", while 39% say "Republican." Notice there are many who do not state any affiliation when given only 2 choices.
But, that's not the whole picture, as is almost always the case with polls.
More working class voters have switched to Republican, making the percentage of college-educated Republicans smaller. Also, Republicans have become increasingly skeptical of a Liberal-run education system that is openly hostile to Conservatives and Republicans.
As a personal opinion, which is held by many, the value of a college degree has been diminished in part by the increased number of degree holders in the US (much more competition for jobs) as well as the cost of education. Student loans are a big topic now, mostly because as schools raise tuitions and fees, the gov't offers what appears to be "free money" until the student graduates. Once saddled with $30K - $300K in debt, depending on the school and degree/s sought, the value of that degree in terms of earnings is almost impossible to overcome. That results in fewer new car and home purchases by young professionals which greatly affects the economy.
One has only to listen to and read what AOC spews forth to understand that having a degree in economics doesn't make you qualified to hold higher public office. I've known people with Harvard degrees who could solve math problems using advanced algebra and calculus, but they couldn't grasp simple concepts of software development, testing and lifecycle management. Math is abstract. Real world concepts are something else. Einstein was a perfect example of how a gift in one area doesn't necessarily translate as genius in other areas.
Having an education is always a good thing, but it should never be the one factor in judging intelligence or wisdom. Until 100% of the population is offered a free college education in useful areas of study (not interpretive dance or transgender studies), you should never use college degrees as the #1 factor for deciding on who should be in public office.
Once you start getting into Masters and PhD territory, you also should have real-world accomplishments and work experience to draw from. Someone who spent their adult years as a "professional student" with no work outside of academia should be scrutinized more carefully.
Hell, there are probably many who would argue that a college degree from any Liberal-run institutions ought to disqualify you from holding public office!!
