This would effectively mean that veto power on everything would be held by any 13 states. For reference the 13 least populated states put together have 4% of the US population. So at minimum blocking all progress needs slightly more than half or just over 2% of the populations support. What you are saying is that senators representing as little as 2% of the US population should be able to overrule the senators representing the other 98%. For practical purposes since we know which side are complete obstructionist what you are saying is that Democrats should surrender control of the country regardless of how much of the vote they win. On the An unholy alliance of Oklahoma, Utah, Alaska, Mississippi, Kansas, Nebraska, Idaho, West Virginia, Montana, South Dakota, North Dakota, Alaska, and Wyoming. Republicans controlling 51% of the vote in states representing 7.8% of the US population could block all progress forever until they got their way. That is to say they would retain a death grip on all progress with as little as half of that 7.8% of the population behind them. This micro minority death grip on our nation would be so strong that the governors veto power hardly matters because anything that wasn't blocked by 1/4 of the senate would never find itself blocked after. In practice the uneven representation that is a design goal of the senate makes it both too easy for flyover states to force their agenda and too hard for policies that are broadly popular to be blocked by the flyover states.
