I don’t “support” any of those politicians, nor would I have the opportunity to vote for them if I wanted to. I imagine that many people vote for them because they view them as better than the alternative. E.g.: Some voters in Georgia may vote for Walker even though he may or may not have paid for an abortion more than a decade ago, because the alternative is a politician who wants taxpayers to pay for abortions tomorrow.
There is a certain logic to that.
