What other people tell you to do can have a lot of impact on who you vote for.
But some people are contrary and won't vote no matter who tells them, or take that same energy and vote for the opposite of what someone else may want.
Or, as in my case and I'm sure many others, they'll take their frustration with things and go look for the political views that appear to resolve your most serious concerns. Sometimes I've had to change my views because of this, as some things have panned out better than others to address what I cared about.
I'm sure politics has something to do with your own personality as it has developed. What irks you is what you want fixed.
Granted, two people (or one person at different times) may find wildly different solutions to the same problem. If you're frustrated with poverty, we all know there are different economic viewpoints on how to combat poverty.
If you're frustrated by immigration, as another example, there is somebody who will tell you what you're looking for.
Politics is based around marketing too, so this part can't be ignored. Your candidate or political party in a sense isn't much different than the cell phone you decide to buy or the restaurant you decide to go to. You want the interface and features that you're looking for, or the ambiance and the fare. And rarely do you get everything you want, or things can go wrong, but possibly it's the best for you still.
...And if not, as I've found, you can always move on.
