Ok... I hear you. But! The presidential campaign is only one item on your ballot. No you won't be able to go in a pop one button and be done. You will have to move through the whole ballot and choose those you can vote for. I have been where you are.  I remember weeping in the polling booth.But not for the reasons you describe.
I saw that I had lived to see every oppressed minority make it on to a presidential ballot. An African American - A Woman - A Catholic - A POW/Veteran.... I felt like a Mom asked to choose between her children as to which ones she loved best. I voted the rest of the ballot, contest by contest. 
Staying home and not voting really isn't an option because it dishonors all those who gave so much that I may vote. Even if you only vote for one contest on your entire ballot.... you can do that! I've been pained by the voting against rather than the voting for style of voting. So if there is only 1 vote for situation I can find -- then that's the only contest I vote in.
