> Isn't it better that I don't vote?

Maybe. I'm not actually that invested in people voting. But that doesn't negate the hypocrisy of complaining when you're, through inaction, endorsing the status quo.

There have been multiple times where the final vote count was the difference of a handful of votes. No one is guilting anyone to vote and some will say that neither party represents what they want and that sucks. But ultimately there has to be one side that even if you don't overall like them you would still rather they get elected. So vote for who you think might be best. And if they have policies you don't agree then contact your representative and say "I voted for you but do not want xyz policy". The more who speak up the better.

No. It is better that you vote. For at the end of the day you can:

1. know you tried to express your wishes

2. know that the outcome is because people expressed their wishes

3. realise the balance between 1. and 2. whether the outcome is as you hoped, and especially if it is not as you hoped.

This is important because hanging back and saying "Well I didn't vote for them!" is by default not supporting democracy as your country views it.

"better" for whom?

I'm not American. And surprise: regardless of your reasons you get judged by the government you put in power, since foreign policy is how the rest of us experience your choices.

And your choices are evidently you're completely okay with the current situation as well.
