What, specifically, isn't transparent? The voting process? Do you vote? I go to my polling place (a school near my home), check in with the nice people working at the table reserved for my election district, sign my name, which is then compared to the signature I provided when I registered to vote, and receive my ballot.
I then fill out my ballot in a privacy area (really just a stand up desk with 2' walls on three sides), put the ballot in the manila folder provided to me with the ballot, walk over to the scanner and insert my ballot.
I then give the manila folder to another nice person stationed by the scanners.
What's more, elections are run at the county level and staffed by folks who live in that county. As such, poll workers are your neighbors.
I suggest you go and work at the polls. They'll even pay you (not all that much, but not nothing either). If you do so, I expect you won't rant online about the vanishingly small amount of voter fraud that actually happens.
The Heritage Foundation has helpfully compiled a list[0] of known voter fraud. They've found ~1600 proven cases of voter fraud since they started cataloging such things in 1979. Since then, more than 1.5 billion votes have been cast in the United States.
1600 fraudulent votes out of 1.5 billion is a fraud rate of 0.0000010666%.
And even if there are 100 times as many cases of voter fraud as the Heritage Foundation has documented, that still only 0.00010666%.
I'd note that there are 3500+ elections (since elections are administered by county) every election cycle. As such, even if there have been 100 times more fraud than documented, that's still only 160,000 votes across ~23 election cycles * 3500+ elections. That's somewhere around two or three fraudulent votes per election.
Given how our elections are administered (there are folks onsite representing every candidate at every polling site and counting center in all 3500+ elections) and the vanishingly small amount of fraud, it's pretty clear that our elections are free, fair and transparent.
Please educate yourself. Go and work the polls with your neighbors. Seriously.
