I vote every election. But, gotta admit, I have the same attitude. My vote really doesn't matter at all. We have absolutely NO say in the primaries....ever....in any election. Then, this state is so red that there is no chance of changing that by my vote no matter if I vote for an R or a D.
Now, where I do feel like I have a say is in more local elections and for my state and federal representatives. But for President.....nope....no say at all.
